Is the above report by go32-v2 before or after you set DPMI to 65535K?  
If it's after, then I don't understand how can that be.  You tell Windows 
to let you use 64MB of DPMI memory, so the sum of the two numbers 
reported by go32-v2 should be 64MB.  This is what I see on my machine.

After you set DPMI memory to 64MB, did it compile from Windows DOS box, or 
does it still crash?

Did you try to bump up CWSDPMI's internal tables size, as the FAQ 
suggests in section 6.4?  If not, please do so and see if that helps.

Another thing to try is to stubedit cc1.exe and enlarge its stack size 
(see section 6.3 in the FAQ).
