[18:06:03] <ev>	 desrt: would you be able to judge whether the problem lies in glib or in whoopsie from that stack trace?
[18:06:46] <ev>	 (the final one, that is - it's got the clearest listing)
[18:07:04] <desrt>	 this stack trace is ... not legit
[18:07:15] <desrt>	 #4  g_main_context_dispatch (context=0x40531cd5 <g_pattern_spec_free+8>) at /build/buildd/glib2.0-2.37.5/./glib/gmain.c:3641 No locals. #5  0x4054132a in g_test_build_filename_va (file_type=<optimized out>, first_path=<optimized out>, ap=...) at /build/buildd/glib2.0-2.37.5/./glib/gtestutils.c:2938
[18:07:20] <desrt>	 this is not possible....
[18:07:43] <desrt>	 neither of those functions call each other
[18:07:47] <desrt>	 even indirectly
[18:07:55] <ev>	 https://launchpadlibrarian.net/147473611/whoopsie2.crash
[18:08:52] <ev>	 but yeah, perhaps we've corrupted the stack inside whoopsie as gdb hints at
[18:09:22] <desrt>	 i'd whip out valgrind as a first step...
[18:09:40] <ev>	 yeah
[18:09:44] <ev>	 will do in the morn'
