You are probably declaring that array inside a function, so it is
allocated on the stack.  DJGPP programs get a 256KB stack by default,
so any local (aka: automatic) array that's larger than that will cause
your program to crash at run time.

See section 15.9 in the DJGPP FAQ list (v2/faq210b.zip from the same
place you get DJGPP) for available methods of enlarging the default
stack.

Alternatively, you could declare the array outside a function, or
allocate its space with `malloc' at run time.

In general, you can't mix object code of different compilers.  If you
have the sources of those TPU's, consider using the GNU Pascal, whose
port to DJGPP is available from the same place you get DJGPP.
