Not responding to Stop-A is unusual. But there's an easy way on
the SS5/170 : the TurboSPARC chip is buggy, and there's a code
sequence that lock up the CPU... and gcc _can_ generate
thay code sequence ! It happens on Solaris, anyway...

try compiling:

#####
int
main(int argc, char** argv)
{
 white(1)
 ;
}
#####

use gcc -O1 (or -O2, can't remember), and lockup your SS5/170... :-(

_maybe_ that's what you are seeing, if it happens only on the 5/170.
