Well, I am running gentoo, kernel 2.6.19-rt15. Amule crashed several times when I have the attente window (attente in french = waiting. Its the window that show the queue of waiting outgoing transferts) on the transfert window. Recompiling with debug and here is the backtrace.

I hope that it will be useful. Not sure because I also get the following when running gdb:

Code: [Select]

(gdb) run
Starting program: /usr/bin/amule
Failed to read a valid object file image from memory.
The last line seam to be a problem. I googled but I am not sure if it is a kernel or gdb bug.

After running amule as above, it crashed. Amule window was still open but frozen.

I am not sure this is a crash. What was the crash message? SIGSEGV? It is unlikely that the program has crashed in dynamic_cast, that would mean that your compiler or c++ runtime is broken.

Please post the gdb crash message, something like "The program has received a SIG*"

Cheers!

Thanks for the replay- Here is the message:

I am doing something that is an overkill, but it will hopefully make my system more consistent. My linux-header was more recent that my kernel, so I downgraded them to the same version as my kernel, re-merged the libc and is at a beginning of a full system recompiling ('emerge -ea world').

EDIT: it worked.
