Hi!
I have experienced similar problems in the Windows environment. I got the
problem nailed into the use of -Oe switch, which (according to documentation)
enables the global register allocation. It could also have been an 'unsafe'
optimization for Windows, only. Anyway, my code now works after exclusion of
the -Oe switch (which incidentally is 'included' in the -Ox switch).
In place of -Ox switch for Windows programs, I'm using...
CL -c -AS -G2csw -Ocgilswz -Zcelp FILENAME.C
