Perl v5.25.4-20-gc2f7c0b* and the attached script trigger this assertion failure. Minimizing the script with afl-tmin caused the assertion to go away.

perl: pp_ctl.c:5140: MAGIC *S_doparseform(SV *): Assertion `!((((_svpvx)->sv_flags & (0x00004000|0x00008000)) == 0x00008000) && (((svtype)((_svpvx)->sv_flags & 0xff)) == SVt_PVGV || ((svtype)((_svpvx)->sv_flags & 0xff)) == SVt_PVLV))' failed.
