I missed the full analysis.  Is it that P::RD depends on a bug in the
current software, or that it's a bug in P::RD that is masked by a bug
in current software, or that an undefined part of the regex interface
changes reactions based on the patch, or that the patch introduces a
*different* bug that triggers bad stuff in P::RD?

That is, I'm unsure why "moving forward" breaks things.  Is it just a
matter that a patch is needed urgently in P::RD?  Or does the patch
also place at risk other unknown code?

Then again, this is the maze-that-is-regex-code, eh?
