There are 3 ways to set the DPMI stack size:
1) Running stubedit (suggest running it a second time to make sure it displays
   what you thought you entered as the default).
2) Use the _stklen global variable (used alone this wastes memory and
   causes some bugs with system/spawn).
3) Add the string "dpmistack 4096000" to the go32 environment variable.

If you make it big enough and get the value properly entered, the stack
fault problem should go away. Note, if you enter a value with stubedit
which it doesn't like, it will set the stack value to 0 without telling
you and you get the default of 256K, which is why I suggest running it
a second time to view what you got.  (For example, 40960000 will not work,
but 4m will work).
