 Fix GHCi segfault in Windows 32bit

 Summary:
 Add missing calling convention to function pointer,
 incorrect `cdecl` calling convention which should be `stdcall`
 on x86 was causing the stack to be corrupted. When it tried to
 return from the function the return pointer would be invalid.

 Test Plan: ./validate
