- in looking around, it might create a frame (for PC_IN_CALL_DUMMY())
and that frame's PC won't have been adjusted.

- since the frame (with a botched PC) may have previously been created,
the top level frame->pc needs to be patched:
/* Make sure that the current_frame's pc is correct. This
is a correction for setting up the frame info before doing
if (target_has_execution && get_current_frame ())
(get_current_frame ())->pc = read_pc ();
