How exactly does this crash and where?  Did you make sure to check that
the original foo pointer was in fact allocated by testing for NULL?  How
are you declaring and using foo in your code?  We need to see actual
example code that doesn't work.  It would also be nice to see a symified
crash traceback (see chapter 9.2 of the DJGPP FAQ).
