This problem does not happen when running directly from the command line or via kdbg, only when run through kdevelop, thus I've selected the mi component, but this may not be correct. I'm debugging a modified version of lincity-ng. I added some mutexes around calls into SDL-image and since then, it began to run very slowly with gdb taking up 98% of one CPU. If I add "set auto-solib-add off" to my ~/.gdbinit then the problem is absolved. A gprof output can be downloaded here: http://glest.codemonger.org/gdb-gprof.out.bz2 Currently, it takes about 3 minutes until I am able to get to a breakpoint. (this gdb executable was compiled with -pg). The output when it did sigabort was this: rip = 0x0; saved rip dwarf2-frame.c:860: internal-error: dwarf2_frame_cache: Assertion `fde != NULL' failed. I should have saved all of the internal commands between kdevelop and gdb. I'll post more information as I'm able to gather it, and hopefully I can get a core file.
