Is this a bug? If so, is it a known bug?

No, this is not a bug, it is a loop, and it is known that loops loop :)

I believe those komodo menu entries correspond to these two perldebug commands

 s [expr]    Single step [in expr] will loop in loops

 n [expr]    Next, steps over subs will loop in loops

If so, is there a known solution?

Yes, use  c [ln|sub]  Continue until position to skip the loop.

Here is a sample session 

$ cat perldebug.loop.pl
#!/usr/bin/perl --
my %f = ( 1 .. 10 );
while(my($k,$v)=each%f){
    print qq[$k $v\n];
}
print "done\n";

$ perl -d perldebug.loop.pl
