Confirmed, using native MSVCRT.DLL from Windows 98 "fixes" the bug. Now 
there is somewhere to look. Possibly the floating point behavior of 
wine's msvcrt.dll (math.c) differs from native, or else some flags are 
modified and not restored correctly. Need more tests to pinpoint the 
root cause (_matherr() ??).
