How to edit linux kernel sources with code::blocks ?
Brane2:
I have got myself Phenom II X4 955 and recompiled whole Gentoo system.
Error is still here. It feels like a race condition of some sort and it seems it is specific aither to AMD or native Quad Core machines.
Can anyone try this on similar machine ?
oBFusCATed:
Are you sure, that you system is stable? You can try prime95 (emerge gimple if I remember correctly) for some hours and memtest86.
But if you have done emerge -e world --jobs=5 successfully, I would say that your system is stable.
Brane2:
System is stable.
I have done memtest86+ checking over night, and reemerged everything with :
emerge -eD --jobs=32 world (MAKEOPTS= -j9)
without a problem.
Jenna:
Can you provide a backtrace if C::B crashes, or do you have a debug report in "/tmp/codeblocks-dbg..." or something like this (don't know the exact location at the moment) ?
If yes please attach it.
Brane2:
When it crashes, it (sometimes) manages to write report in /tmp/codeblocks_dbgrpt_XXXX:200908ddTzzzzzz.
I recompiled glibc,glib,gtk+ and wxGTK with -ggdb in order to get debug symbols.
I ran it under gdb, but since C::B opens a few threads, it is unclear to me which thread did trigger SIGSEGV (Segmentation fault), altough my bet would be on default, 6-th thread:

I have also attached also a couple of xml bug_reports ( renamed to txt to get by forum filters ).
