I am currently trying to migrate an existing perl infrastructure from perl 5.005/linux 6.22 to 5.6.0/linux 7.1

Most of my applications work fine, but I have found a few regex commands that do not work in my new environment.

Here is an example - original:
 if ($sb =~ /<$fi>\s*(.*?)\s*<\/$fi>/gis) {

works well on my old environment, but not on my new. If I make the following modification the regex begins to work again
-modified:
 if ($sb =~ /<$fi>\s*(.*?)\s*<\/$fi>/is) {

i.e. the global modifier causes the expression to stop working.

Does anyone have any thoughts as to what might cause this?
What I am wondering is if perhaps this is a bug in perl 5.6.0 or if perhaps I have some configuration setting incorrect in my new environment.
