Your sample program is trying to use almost 1 megabyte (!) of stack 
space. No wonder it crashes. Are you sure that your program jack_fst is 
trying to allocate such an enormous amount of stack space? Most (sane) 
programs would just declare a pointer and allocate the required space 
via malloc() or HeapAlloc().

Where can somebody else get a copy of jack_fst? Is there a public 
download somewhere?
Maybe jack_fst corrupts the stack in some strange way that was 
misdiagnosed as as request for a 1Mb stack?
