Which ebuild and version is this about? Don't see any such thing in the tree. Also see http://www.gentoo.org/proj/en/qa/backtraces.xml Sorry: x11-plugins/bfm I already followed http://www.gentoo.org/proj/en/qa/backtraces.xml but get no usable info. Rigth now waiting for next crash, I'll post the result when it happens Backtrace not very enlightning: gdb /usr/bin/bubblefishymon --core ./core --batch --quiet -ex "thread apply all bt full" -ex "quit" (no debugging symbols found) Using host libthread_db library "/lib/libthread_db.so.1". warning: Can't read pathname for load map: Input/output error.

(In reply to comment #5) > Well, the above backtrace is just useless; I know :-(( > recompile all the dependencies as > well. Any idea what dependency may cause the problem? I doubt it is gtk+. Additional Info: x11-plugins/gkrellm-bfm-0.6.4 shows the same behaviour. I encountered this bug too with x11-plugins/bfm-0.6.4-r1.
It seems that if optimizations are enabled (-O1 or more) it segfaults as soon as memory usage increases enough for the water level to reach the top of the program's display. With optimizations disabled (-O0) the problem disappears. Here's a backtrace:
* gdb /usr/bin/bubblefishymon --batch --quiet -ex run -ex "thread apply all bt full" -ex "quit"

To make it crash quickly, run it, and at the same time do something that uses a lot of RAM, e.g.: perl -e 'while (1) { $x .= "." x 10000; }'

CFLAGS="-O1 -pipe -ggdb"
(initially I had CFLAGS="-O2 -march=pentium4 -msse2 -mfpmath=sse -fomit-frame-pointer -pipe -ggdb", and trimmed them for the above backtrace - although as far as I can tell, the extra options don't make any difference)
Could this bug be reopened? Or should I report this upstream?
