For me (on 4.7), SHAPE and LBOUND work, only SIZE and UBOUND cause an ICE.

The segfault happens for SIZE and UBOUND at:

 Invalid read of size 4
    at 0x5383E0: gfc_simplify_size (simplify.c:5553)

(When patching, remember that UBOUND((X)) and UBOUND(X) are different, it the
lower bound of X is not 1.)
