--- Comment #4 from jakub at gcc dot gnu dot org 2010-03-08 11:50 --- That seems like you've tried to debug xgcc instead of cc1. Of course the backtrace from cc1 is interesting, not from xgcc (which doesn't SIGBUS). Run xgcc with additional -v option, and copypaste the cc1 command line it invokes and run that under gdb. Or instead of -v use -### and copypaste the cc1 command line from there. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43287
