PATCH: [perl #101940]: BBC Tk
This commit that turned up this bug turns out merely exposes an
underlying problem that could be generated via other means.
regcomp.c was looking at the SvUTF8 flag on the input pattern before
doing an SvPV on it. Generally the flag is considered not reliable
unless checked immediately after a SvPV.
I haven't been able to come up with a simple test case that reproduces
the bug. I suspect that XS code is required to trigger it.
