Subject: S_reg: Assertion `(pRExC_state->parse) < (pRExC_state->end)' failed (regcomp.c:10187)

While fuzzing Perl v5.23.9 (v5.23.8-11-g71dfb35) with American Fuzzy Lop, I found a script that triggers an assertion failure: ~/perl/perl -e '0,qr{(}' perl: regcomp.c:10187: S_reg: Assertion `(pRExC_state->parse) < (pRExC_state->end)' failed. In contrast, Perl v5.20.2 throws the following: Unmatched ( in regex; marked by <-- HERE in m/( <-- HERE / at -e line 1.
