64-bit compatibility

I get segfault in libgst/oop.c:740 in 64-bit mode.

problem seems to originate here (line 735):
int size = SIZE_TO_BYTES (TO_INT(oop->object->objSize));

looks like TO_INT() macro does something wrong and size is assigned to incorrectly large number…

related definitions:

objSize is defined as OOP

typedef struct oop_s *OOP;

struct oop_s
{
gst_object object;
unsigned long flags; /* FIXME, use uintptr_t */
};

#define TO_INT(oop) \
((intptr_t)(oop) >> 1)

do I correctly understand, that the problem is related to that "FIXME"?

No, unsigned long is exactly to same size as FIXME and besides flags is
not being accessed anywhere. Just to be clear, I run on Linux 64-bit
all the time.
