It looks like this was fixed in 4963771dd10435273997ef50267b3ebd07dfb80b (v5.21.0-429-g4963771), but that patch doesn't appear to be directly applicable to maint-5.20 since it depends on the ?...? operator being removed. Tony

Here's a simpler crash case (attached) tony@mars:.../git/perl$ ./perl ../125697b.pl Segmentation fault tony@mars:.../git/perl$ od -c ../125697b.pl 0000000 m \n # 0000003 which feels familiar. Tony

This is fixed in both supported releases, so closing. Tony
