It's this.  The default stack in DJGPP programs is 256K, and does not
grow dynamically.  It's no wonder you're getting a stack fault here; I'm
amazed you didn't have worse problems.

FYI, x is not being declared statically; it's being declared
automatically.  If you use the static qualifier, or declare it globally,
your program will work.

For information on setting the stack size of DJGPP programs, and other
trivia, see chapter 15.9 of the FAQ (v2/faq210b.zip from SimTel or
online at http://www.delorie.com/djgpp/v2faq/).

hth!
