From @schwern

My co-worker ran into this problem. It appears that a compiled regex
used inside a /x pattern needs to be /x as well. The following
demonstrates​:

$pat = 'foo';
$c_pat = qr/foo/;
$c_pat_fixed = qr/foo/x;

$string = 'foo';

$\ = $/;
print 'normal​: ', $string =~ / $pat /x ? 'Yes' : 'No';
print 'qr​: ', $string =~ / $c_pat /x ? 'Yes' : 'No';
print 'fixed qr​: ', $string =~ / $c_pat_fixed /x ? 'Yes' : 'No';

I've noted this failure under 5.005_03/Linux and 5.005_02/Linux

Is this using sendmail? If I remember correctly, sendmail
only allows you
to lie about the From address if you are a 'trusted user'.

A temporary solution might be to add a 'Reply-to' list of p5p and the
originator​: people's autoquoting will still claim that you wrote the
message, but at least they'll be able to reply to the correct person.
(In fact, the list should probably have perlbug rather than p5p so
that replies get picked up by the bugtron.)

Ugh. Reply-To's are awful. If it takes running sendmail as a
trusted user, by all means run the thing as a trusted user.

If that can't be done for some reason, I think the bugtron should
simply do the same thing 'dist' (in MH) does. I'm no sendmail
expert, but sticking in a Resent-From header may do the trick.
