Hi folks,

I got a segmentation fault running the CVS from 21 June. Here is the backtrace. I hope it is useful.

Code: [Select]

[Ezeltje]

I got this segfault again today. Here is the first bit I forgot to include above:

Code: [Select]

Program received signal SIGSEGV, Segmentation fault.

44        inline bool

Uptime of approx. one day. Amule was running in the background in both cases, so I don't know what specific action caused it.

[phoenix]

Looks like a crash in wx. Are you using Wardevil's packages for wxWidgets or FC5 distro packages?

[Ezeltje]

I am using the FC5:

Code: [Select]

]$ rpm -qa | grep wx
wxGTK-2.6.3-2.6.3.2.1.fc5
wxGTK-gl-2.6.3-2.6.3.2.1.fc5
wxGTK-devel-2.6.3-2.6.3.2.1.fc5

[phoenix]

Try wardevil's:

http://www.amule.org/amule/thread.php?threadid=10291&sid=

http://www.savefile.com/projects/166294

[Ezeltje]

OK, I have now installed wardevil's RPMs. Thanks for pointing them out; I wasn't aware of them. We'll see how this goes....

[Ezeltje]

Hi again phoenix,

Alas, this combination only ran for less than an hour last night before crashing. This isn't the complete backtrace and may be of limited use, but here is what I have:

Code: [Select]

----------------------------=| BACKTRACE FOLLOWS: |=----------------------------
Current version is: aMule 2.1.3 using wxGTK2 v2.6.3 (Unicoded)

It looks like another wx* problem, no?

At this point, what do you recommend I do? I can try running amule with gdb again to get full backtraces, but I will have to recompile as my current build doesn't run with wardevil's wx packages (library mismatch error).

[phoenix]

Hum, no, this one does not have the necessary info to conclude anything. You can try gdb. But do recompile wx AND aMule with debug info. Maybe you can try to find out why wardevil's packages do not work. They are supposed to work.
