--- Comment #3 from Daniel Starke <daniel.f.starke at freenet dot de> --- Created attachment 32720 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32720&action=edit gdb output with backtrace for -falign-functions I have tried building GCC 4.9.0 with other optimizations enabled and found out that -falign-functions also causes a SIGILL when executing gcc in state 2. Please find the GDB output for this attached. No other optimization enabled by -O1, -O2 or -O3 caused any problem so far.
