[perl #37836] Simple Regex causes SEGV when run on specific data

This bug may be fixed, but the test for it in t/re/pat_rt_report.t is
wrong, and works only because the single character ANYOF node is being
optimized into an EXACT node.  If you add any other character to the
class, the optimization goes away and the test fails.  It does not cause
a segmentation fault, but you do get the correct error message that this
is malformed utf8.

I'm not sure how to fix this without further research.
