The complete line is:
if (!aglSetDrawable(togl->aglCtx,
# if defined(TOGL_AGL)
((MacDrawable *) (window))->toplevel->grafPtr
# else
((MacDrawable *) (window))->toplevel->portPtr
# endif
)) {
togl and togl->aglCtx are known to be non-NULL (otherwise it would
have crashed before then). Can you try the following:
print ((MacDrawable *) (window))
print ((MacDrawable *) (window))->toplevel
print ((MacDrawable *) (window))->toplevel->grafPtr
