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

actual version: x11-plugins/bfm-0.6.4
Well, the above backtrace is just useless; recompile all the dependencies as well.
(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" [Thread debugging using libthread_db enabled] [New Thread 0xb738f710 (LWP 17327)] Program received signal SIGSEGV, Segmentation fault.

Or should I report this upstream?
