I've now tried a 64bit version and sure enough, that one always crashes with a SIGBUS when returning from the signal handler, even if the handler doesn't do anything. Warrants a radar, I'd say. I've put the adjusted 64bit version of the test program below (which, as I said, crashes even if you remove all code from "signal_handler"):

Found the solution! Change

...

sa.sa_flags = SA_SIGINFO;

into

sa.sa_flags = SA_SIGINFO|SA_64REGSET;

heh. I added that to my FPE test program and the machine hung hard. I had to power cycle :-) it's a imac G5. -brad _______________________________________________ Do not post admin requests to the list. They will be ignored.
