Error: free(): invalid next size (fast):
location: linuxexchange.com - date: July 22, 2015
What is this strange error I'm getting? I'm compiling C++ using g++ on Ubuntu 10.10. It pops up randomly when I run the executable (maybe 2 times in 8 hours, with 10 compiles an hour). However, if I make clean and recompile it goes away most of the time.

Memory error: free(): invalid next size (fast)
location: linuxexchange.com - date: January 12, 2013
I'm trying to implement a radix sort, and this code produce a memory failure:
(free(): invalid next size (fast))
The code is the following:
unsigned int * radix(unsigned int *x,int n, int g,bool verbose)
int elem_size = sizeof(unsigned int)*8;
int mask = ((1<<g)-1);
float num_rounds= ((float)elem_size/(float)g);
int B = 1 << g; // 2^g BTW
vector<unsigned int> buckets[B];
// begin radix sort
for( unsigned int round=0 ; round<num_rounds ; ++round)
for(int elem=0 ; elem<n ; ++elem)
// calculate the bucket number:
unsigned int const bucket_num = ( x[elem] >> g*round) & mask;
// more stuff
GDB states that the error is inside push_back, but elem is always smaller than n (where n is the size of x). So, I thought that it could only be on bucket_num. Ho
MPlayer Error Message Error Opening/Initializing Video Out Device
location: linuxquestions.com - date: June 25, 2006
I have installed Mplayer. It appears as though the install went fine. However, I can't play any video because I get an error message that says "Error Opening/Initializing The Selected Video Out (-vo) Device". I can't seem to be able to play anything with it DVD or video files. Other than that, seems like the install went okay. Video card is an ATI X800 and I have managed to get 3D working with it. Here is a copy of the message received when trying to play a DVD:

[SOLVED] problem with ssh/putty. Error: "connection timed out"
location: linuxquestions.com - date: June 15, 2012
I'm trying to ssh from my windows machine using putty into a Linux VM for my certification studies. This is password based authentication, so i'm not using any pub/private keys. Not entirely concerned about that right - I just want things to work first then i'll get to that.
I'm running a relatively new install of mint, and the sshd daemon already up and running. I'm able to ssh to the guest localhost within the VM, but I can't ssh into the VM externally from host (windows). I disabled ufw to see if that would be the culprit but the problem persists.
here's my sshd_config file.

glibc detected memory corruption
- date: April 17, 2011
I reinstalled Kubuntu few days ago and now getting errors on any attempt to install software about glibc detects memory corruption.
As result, any packages finish their installation process but have problem in post-installation scripts. I think it means clearing garbage. And actually it doesn't work.
I can't understand: the problem is inside glibc library or grub-probe (where it appears) or somewhere else?
How to fix? Thanks.

*** glibc detected *** corrupted doublelinked list: 0xb7e15938 ***
location: ubuntuforums.com - date: February 9, 2006
Hi all. I have a C++ program that I wrote. The code compiles without any error or warning message. But when I execute it, I get the
*** glibc detected *** corrupted double-linked list: 0xb7e15938 ***
message. This only happens when I chose certain input parameters. It works flawlessly under other conditions. Can someone please help me make sense of this error message? I want to know which part of my program is causing trouble.
problem in executing c program: glibc detected
location: ubuntuforums.com - date: May 21, 2012
I'm trying to execute a program written in c and I get this message:
*** glibc detected *** ./program-name : free(): invalid next size (normal): 0x08a78dc0 ***
While compiling I don't get any error message and I'm sure the problem doesn't come from the program because it's been already used. So that I think that the problem is in the version of glibc that I use.
Here is what I have installed on my ubuntu 11.10
-gcc version 4.6.1
I tryed to type "rpm -q glibc" and it says that it's not installed, but when I type "sudo apt-get install glibc" I get the following answer: "impossible to fnd the package"
I am not an expert, neither with c language nor with Linux, so I have no idea where the problem could be!
Thanks a lot!!

I've been running a script developed by someone else (downloaded from http://code.google.com/p/force-distribution-analysis/). Everything had been fine - however, when I ran one of the commands (g_fdatools) I originally got the following error ...

I looked through the forums and a lot of places mentioned using the " export MALLOC_CHECK_ = 0" to prevent this error from crashing the system. When I did this, it still crashed, this time with a segmentation fault (no other information given).
I figured I should go back and work through the original problem rather than just tell it to ignore so I changed MALLOC_CHECK back to 3 but the glibc error had changed to ...

glibc detected corruption errors

This is weird. So, I started getting an error message from a qt application I wanted to add a new feature to. The error is: *** glibc detected *** ./myprogram: double free or corruption (!prev): 0x08df0148 ***
A quick hit on google revealed what I thought would normally be the cause, a bad free(). Now, I had upgraded my harddrive to an ssd recently and the code was just copied over from the old hdd, so I thought maybe there was something wrong with my build environment. After a bit of searching, I couldn't find anything. I think I used the same parameters to recompile it and my environmental variables seem to be good.I finally just plugged in the old drive and ran the unmodified, untouched program off of that one. Same error. Now I didn't remember getting that error the last time, so I rebooted into the old drive and ran it. No errors. And then I ran my newly-compiled, fresh-off-the-ssd version and it worked perfectly. Very weird.
If anyone knows what might be causing this, any hel
