Reported 2008-04-11 11:56:28 PDT
- This seems to happen whatever the loaded url. - It doesn't happen when built with no optimization (-O0) - It happens with or without the patch from bug 18367 applied - It doesn't crash when built with gcc 4.2.3 - Only tested on Gtk Port - Full backtrace follows: Program received signal SIGSEGV, Segmentation fault.

Comment 1 2008-04-11 12:24:12 PDT
FWIW, it was built with CFLAGS="-O2 -g" CXXFLAGS="-O2 -g" ./autogen.sh, which means it is not a debug build, despite debugging symbols being there to provide a full backtrace.
