Huh. But that case is in fact *broken*, because GDB will use stop_pc
incorrectly: for example, the check whether we are about to continue
at a breakpoint will look at stop_pc, but then continue at $pc. Also,
if we issue a "step", the step range will be set according to the line
at stop_pc, but we will actually continue at $pc ...
It seems to me just about every current user of stop_pc *really* wants
to look at regcache_read_pc (get_current_regcache ()) ...
Bye,
Ulrich
