Here's an ugly way to do it - have the program 'mark' the start
address someplace.  Either a known file name, an environment variable,
a known port name, etc.  Then have the second task deallocate the
memory and remove the 'marker' when it's done with it.  Make sure
both tasks agree on how much memory is allocated, or allow the
second one to find out.

Don't use malloc, the C compiler's runtime library will deallocate
the memory when you exit.
