I've been having these crashes quite often. Not much I can do to reproduce them. They seem to occur randomly, about 10 minutes after I open amule.

I'll see if I can get another bt of the next crash and see if it dies at the same spot.

ProcessExtPacket seems to be receiving an underflowed size, which I guess causes the segfault.

This is on gentoo, amd64.

(this goes on seemingly forever until about 1000, after which I quit)

Do you guys need me to compile my wxGTK with debugging symbols too?

[allanw]

It just segfaulted again, and in the same place, so it looks reproducible (but I'm not sure what kind of packet to send to get it to do this). Bad client, maybe?

Yay, more segfaults. This time I went to another server to see if I can avoid that client. This time it seems to crash in a different place. (ignoring the backtrace-generating functions)

[Xaignar]

Was there any ouput on the console before the crash?

[allanw]

Not anything except "Segmentation fault (core dumped)". The other messages were several minutes old.

[Xaignar]

Ok.

[Xaignar]

Can you elaborate a bit on your system information?

EDIT: Also, there's something rather strange going on. If you look at frame #7, the value of nErrorCode matches the packet-size, but if it really was this value when the function was called, it wouldn't even proceed that far.

EDIT2: Can you try running "make check" in the in the cvs-snapshot folder?

[allanw]

Not sure what other information you want.

I'm about to try with -O0, perhaps optimization is messing up the code execution.

[Xaignar]

Which ebuild do you use?

[allanw]

make check tells me all 5 tests passed.

amule with -O0 has been running for about 10 minutes without crashing, yet.

I got my ebuild from fluidportage:
http://www.zugaina.org/gentoo/fluidportage/portage/net-p2p/amule/amule-20101010.ebuild

I'll try the one from this forums if I continue having problems.

Sorry for not specifying it, but did you export your original CFLAGS and CXXFLAGS before running "make check"?

[allanw]

Yeah, the make check stuff was compiled with " -march=athlon64 -O0 -ggdb3 -pipe"

Doesn't only configure check CFLAGS anyway?

[Xaignar]

Err, yes, sorry. The exports would of course have to be done before configure was run.

Hmm, I don't see it crashing yet. Perhaps it's a side effect of using -Os. I'll increment optimization and see what point it starts crashing.
