The summary pretty much says it; perl 3.0 pl12 is dumping core on trying
to debug Tom Christiansen's makewhatis.pl, posted recently.  I've narrowed
it down to the point in cons.c:make_sub(), line 78; at that point, 
cmd->c_next is NULL, so of course the assignment to cmd->c_next->c_flags is
not very copacetic.  I have not been able to determine the cause yet; I'm
remaking with LEAKTEST on.

This seems to be at the point just after the last subroutine in the target
perl program is read (i.e., on the make_sub() call for the last sub in
makewhatis.pl, which is extract_names); not sure if that will help.
