The most likely place the problem would be is in one of the other routines that
use "long double".  I see (after my patch):
1) dlls/msvcrt/scanf.h:325 (the whole family of scanf functions)
2) dlls/msvcrt/wcs.c:396/491 (MSVCRT__wcstod_l)
3) dlls/ntdll/string.c:999 (NTDLL_vsscanf)
So, a WINEDEBUG="+msvcrt,+ntdll" looking for these functions might help narrow
it down.

However, the x87 FPU is also used by d3d - so there are some other
possibilities if it's not one of these routines.
