case-insensitive regexp bug in perl 5.17.x?

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

This test demonstrates code that has worked for me until 5.17.0. It fails in 5.17.0 and higher.
#!/usr/bin/env perl use strict; use warnings; use Test::More tests => 2; my $str = ' Foo '; # uppercase breaks 2nd regex my $pattern = 'foo'; utf8::upgrade($str); utf8::upgrade($pattern); my $re = qr/$pattern/i; my $re_optional = qr/(?i:.?)$pattern/i; like( $str, $re, "re" ); like( $str, $re_optional, "re_optional" );
Am I missing something?

    Did you post to P5P list? That is a development version, so you should probably post the question there. Also 5.17.4 was released, you could try with that version (if you haven't already).
      Thanks. Opened RT ticket via perlbug.
