(perl #131646) make the test less fragile
The original pattern "UXp>" with the $_ that causes the failure, 5,
so we end up packing exp(5) or 148.... with U packs:
- U (148), producing C2 94, with the UTF8 flag set
- X - back up a byte,
- p> - write the address of PL_sv_no's PV in big-ending
The final p> will typically overwrite the 94 with a zero on 64-bit
systems, but with the smaller address space of 32-bit systems that
high-byte is more likely to be a valid continuation byte, causing
the comparison to fail.
Instead just pack a zero byte.
