Bug#623380: vlc: malloc(): smallbin double linked list corrupted: 0x00000000024952a0
Vincent Smeets
Version: 1.1.7-3
Severity: important
Opening the link http://www.q-music.nl/asx/q-music.asx with vlc gives a
core dump. I start vlc with the command:
vlc -vvv >vlc.out 2>&1
and then open the media stream. It starts opening the stream and then
(before playing anything) vlc quits. The terminal shows then the
following lines:
vincent@PC-Vincent:~$ vlc -vvv >vlc.out 2>&1

Could you produce a valgrind trace
Also could you tried which package owns
/usr/lib/tls/libnvidia-tls.so.260.19.44 and try without it

I didn't get any errors by using valgrind. I have tried it multiple
times with the command:
valgrind --log-file=vlc.valgrind --leak-check=full vlc
I have attached the valgrind file.
The file libnvidia-tls.so.260.19.44 is from the package
libgl1-nvidia-glx from the non-free debian repository. It is part of the
kernel driver for my nvidia graohics card.
As an additional info:
The plain 'vlc' command doesn't always give a core dump. Sometimes I get
a core dump and when I try it again, it can work without an error. It is
not predictible. I think the error is somehow related to the scheduling
of the threads. There is probebly some memory access that is not
protected against concurrent threads. I just also got the error:
vlc: double free or corruption (out): 0x0000000002a246a0
I have tried it about 20 times with valgrind but didn't got the error.
Persumably is the scheduling different by using valgrind.

Vincent
