  The 'malloc.c' supplied with perl patch 3 is generating this error
when it finds it's header trashed on a free. Either this malloc is
buggy, or perl is trying to free bad addresses. I'd rather suspect the 
malloc. Possibly a sign extension problem? (I'll dig deeper tomorrow)
I notice in patches 4-10 some reference to the built in malloc code.
So maybe it has been fixed. (We have been waiting till it's stable :-) )

  I have re-built perl 4p3 with the SUN malloc code, lets try
it tomorrow on your 'killer' code. .. :-)

Look at page 261 of Programming Perl.
