Looks like uintptr_t and __mf_uintptr_t are somehow different types.
__mf_uintptr_t is defined via

typedef unsigned int __mf_uintptr_t __attribute__ ((__mode__ (__pointer__)));

uintptr_t is defined by some system header file.  I would guess that the
types normally wind up the same, but in the C library that you are using
they somehow wind up being different.

Probably mf-runtime.c should be changed to use __mf_uintptr_t rather
than uintptr_t.
