[perl #128680] Suspected memory leak with match operation

By eyeballing the memory usage, I have determined that this bug was fixed by the three commits:
ee072c898947f5fee316f1381b29ad692addcf05
7eec73eb790f7c4982edfc28c17c011e8a072490
0bf54b1ecaec8f6d80845d6cb77d62f8c9f4c415

and that this ticket is the same as #128313 (which I'm merging it into).  That ticket only showed a leak with 'use re "strict"'.  This shows it can happen outside that.

Since this is a regression, this is a candidate for fixing in a 5.24 maintenance release.  I have created a patch which has those 3 commits merged into one (the 2nd and 3rd were modifications of the first) and attached it to this message, and am adding it to the blocker and maint votes lists
