I upgraded a machine to the latest Ubuntu and got Perl 5.34.0, which included a problem with the debugger: 

  DB<4> v

My friend Google brought me to this page that had links to the necessary patch to perl5db.pl on github, bringing the script from version 1.60 to 1.60_01.

And, of course, the patch worked just fine. What a great community. Thanks for the patch!

PS: Ugh, sorry -- the problem was that the v command that I use a lot (Where am I? Oh, there I am!) crashed the debugger. The patch solves that problem.
