This looks pretty strange. Moreover, it's not clear to me what the
benefit is of showing the sizeof scanflags_t, which isn't the amount
attempting to be allocated anyway, it's sizeof scanflags_t * 32,
right? (The assignment in the multiplication in the allocation is
pretty shady, too.)
But really, why does %ld expect a pointer? Is lerrsf_fatal some
esoteric thing that doesn't take varargs or use normal format strings?
If not, just use %zu and get rid of the cast rollercoaster? The
pointer cast is pretty astonishingly-odd anyway.
Juli.
