Did you try disabling floating point exceptions? A lot of C code
assumes that floating point exceptions are disabled (since that's
what the C library does on startup).
Another possible problem can be the fact that FPC currently is not
fully compliant with the x86-64 ABIs. In particular, the following
data structures are wrongly handled when passed to cdecl/stdcall
routines *as value or const parameter*, and when they are returned
from a cdecl/stdcall routine:
* arrays <= 16 bytes of integer or floating point numbers (handled
wrongly on all x86-64 platforms)
* records <= 16 bytes containing floating point numbers or arrays of
floating point numbers (handled wrongly on non-Win64 platforms under
most, but not all, circumstances )
I'm working on a fix for that, and it's finally almost finished.
