It is quite probable that OpenBSD forbids executing code in the C  
heap, for security reasons I guess.  Usually there is a way to tell  
the operating system that a certain range of addresses contains  
executable code.  I have no clue what this is on OpenBSD.  If you do  
find out or someone on the list knows, please let me know.
