Bug #119321 for Config-Std: t/undef.t: Unescaped left brace in regex is illegal here in regex

This is a bug report for: Config-Std-0.901 Due to unescaped left braces in some regular expression patterns in your code, your module won't work on 5.26.0. The CPAN Tester automated testing service cannot test your distribution on new versions of Perl until it is fixed and any modules that depend on yours will not work either. Please see: http://matrix.cpantesters.org/?dist=Config-Std Here is a link to all modules that depend on yours: http://deps.cpantesters.org/depended-on-by.pl?dist=Config-Std We would appreciate help in sorting this out before the new version of Perl is released in May of this year. These errors are quite easy to correct and I would be happy to lend a hand. I'm including a log file of my failure to build and install using "cpanm". Thanks! Jim Keenan
