Simon appears to be correct, and I appear to be wrong. It seems that  
the BSD malloc/free stuff changed at some point.  Excerpt from the  
malloc man page on a 6.1 FreeBSD install:

"A side effect of this architecture is that many minor transgressions on
     the interface which would traditionally not be detected are in  
fact
     detected.  As a result, programs that have been running happily  
for years
     may suddenly start to complain loudly, when linked with this  
allocation
     implementation."

Many apologies for passing along inaccurate information. Anyway know  
when this changed?
