Hi,
I upgraded from perl 5.16 to 5.22.
I have hundreds of scripts that I just cannot modify.

This now fails: 

perl -e 'my $var = "hello"; $var =~ s!(?<=\D[01] file)s!!ig;'

[download]

It seems that the i option produces the variable length failure because of unicode processing of regexps.

So my question is:
Without modifying this part of code, what can I do to get the same normal behavior I had with 5.16, without downgrading back to 5.16?
I can recompile 5.22 w/ different options if needed.

Thank you!
