Using M-x compile in perl mode, this line can be found just fine,

Missing argument in printf at ./p line 44.

But this throws M-x compile way off track,

Useless use of a constant (6) in void context at ./p line 44.

Do you have a perl file that allows us to reproduce this bug?

Unless you can provide an example to allow us to reproduce the error,
it's unlikely that any progress will be made on this bug report.

Pick your poison:

perl -wE '{my %a; $a{b}=(a=>1,b=>2,c=>3);say %a};'
perl -wE '{my %a; $a{b}=(1, 2, 3);say %a;}'


Regards,
Achim.

Try this file:
use strict;
use warnings;
(22, 1);
Compile with "perl file".
You will even see emacs thinks the error is to be found on "line 22".

I can't reproduce this on master.

Me neither, so I'm closing this bug report.  (Although it does add a
link to "constant (22)" in addition to the "line 3" link, but that first
link doesn't point to any file.):
