Well, some compilers will dislike the attempt to cast a (char *) into
a (int (*)()) ; in fact I think some will call it an outright error
(not just a warning).  But in any case it is _not_ portable to the 3b2,
because all programs are pure -- you can't goto/call data space, nor
can you read from the instruction stream.  Some sort of chastity belt
in the hardware, I think.
