You did a "make all" inside the top level of the source? Then you have 
also rebuild the compiler. Simple as that... ;)

Since you also disabled optimizations by passing "OPT="-gl -O-"" to the 
"make all" step there shouldn't be anything missing, so the heap 
corruption does indeed seem more likely.
