--- Comment #11 from Kai Tietz <ktietz at gcc dot gnu.org> --- (In reply to Denis Excoffier from comment #10) > Created attachment 32595 [details] > gdb session catching signal SIGABRT Thanks for the debug-log. Could you please attach the backtrace starting from the fancy_abort call? (That what you see after up 7). The issue here is that deregister is called without any register object (ob). Therefore is got NULL.
