I identified the problem now: "secofs" value returned by function
"FindSectionCoff" in file "exeinfo.pp" is always 2,048 bytes too small.
2,048 (or $800) is the size of the go32 EXE stub.

I failed to find an elegant solution, that doesn't break PE32 or
PE32PLUS. Maybe somebody else, who's more familiar with FPC's source
code, could fix this?! Of course, I could assist as a tester.
