If the C/2 libraries are like the MS-C libraries (and I think
they are very close), you need to call _beginthread to start the
thread rather than DosCreateThread.  _beginthread  initializes
some per-thread static data (stuff like errno), which also includes
the stack size used by the stack checking routine.  Calling
DosCreateThread directly will result in problems like what you
are seeing.
