Have not used TP's EXEC function myself, so I'm out on a limb
here.  But, in general, when you do this you have to free
up enough memory  (all memory is allocated to YOUR program
to begin with) to run the child process.  I don't know how
much memory FASTGIF requires (I know VUIMAGE requires 150K
memory without limiting image size), but there has to be
sufficient memory to load and execute the child process.
This could be your problem.
