After bringing my version of perl up to patch level 12 on a sparcstation1
and a SUN 3/60, I noticed that "perl -d prog" dumped core occasionally.
I narrowed it down to explicit returns inside a subroutine.
This happens on both the sparcstation and the sun3. The scripts work fine
when run normally. So the work around is obvious: write your programs
in such a way that you either don't use explicit returns or so they work
first time and need no debugging :-)
Seriously, I have just been using perl.old for debugging purposes.
This program dumps core when run under the debugger:
---------------
#!/usr/bin/perl
sub bug {
return 1;
}
&bug;
---------------
