possible bug in the perl debugger in perl 5.34

mandarin has asked for the wisdom of the Perl Monks concerning the following question:

Dear fellow monks,

I would like to confirm that I am experiencing a bug in the perl debugger shipped with perl 5.34, which is perldb.pl version 1.60

If I type the debugger command 'v', there is a weird error message:

 
# perl -de '1;' 

Loading DB routines from perl5db.pl version 1.60
Editor support available.

Enter h or 'h h' for help, or 'man perldebug' for more help.

main::(-e:1):   1;
  DB<1> v

This happens in the perl:5.34 docker container I pulled from https://hub.docker.com/_/perl

I just compiled 5.34 and confirm the problem. See https://github.com/Perl/perl5/pull/18900.	[reply]

Oops, I ran `git fetch` but forgot to actually `git merge`, so I started fixing the problem that had already been fixed. My fix is more complete than the existing one, though: #19171 `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]
