[ "overflow with warnings/disallow for more than 31 bits",
# This tests the interaction of WARN_ABOVE_31_BIT/DISALLOW_ABOVE_31_BIT
# with overflow. The overflow malformation is never allowed, so
# preventing it takes precedence if the ABOVE_31_BIT options would
# otherwise allow in an overflowing value. The ASCII code points (1
# for 32-bits; 1 for 64) were chosen because the old overflow
# detection algorithm did not catch them; this means this test also
# checks for that fix. The EBCDIC are arbitrary overflowing ones
# since we have no reports of failures with it.
