amule crash #2
« on: March 01, 2006, 03:45:13 AM »

Almost the same bug as before. I guess I was trying to switch to the amule window by double clicking its icon in the docker. It didn't yield any result, so I clicked the amule icon in the xfce4-iconbox and saw an empty window. So it's another amule crash, and here's its backtrace:

Most of the crashes came from ::DrawCell functions, could this be a thread synchronization issue?
Could this be a bug in wxWindows (or bug caused by -O3 for wxWindows)?

Also, I've read some other bug reports, and I'm going trying recompiling wxWindows with less 'aggressive' CFLAGS,.
Right now, i was using these (from my make.conf - gentoo):
CFLAGS="-march=athlon-tbird -mtune=athlon-tbird -O3 -pipe -fomit-frame-pointer -fno-stack-protector -fno-stack-protector-all -mmmx -m3dnow"
CXXFLAGS="${CFLAGS}"

baron@baron ~ $ wx-config --cxxflags
-I/usr/lib/wx/include/gtk2-unicode-release-2.6 -I/usr/include/wx-2.6 -DGTK_NO_CHECK_CASTS -D__WXGTK__ -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D_LARGEFILE_SOURCE=1 -DNO_GCC_PRAGMA
