There is a bug in most 386DX processors that causes corruption if you load
a value from memory right after executing a "popal" instruction. The 1.0.4
RTL contains this code sequence several times and this probably causes the
problem. This has been worked around in version 1.0.6 (the beta is already
downloadable, the final version should be available by next week)

I think the Dos version of FPC includes cwsdpmi.exe. As long as the
directory containing that utility is in the path, it should be executed
automatically when starting a go32v2 program if there is no dpmi server
loaded yet.

That's probably also due to the 386DX bug.
