I briefly looked into getting that test working, but couldn't figure it out quickly, so I have reverted the fix for the regex reentrancy abort, in emacs-25 commit 8e84823f3f06714d0668060d62456cf7e3100e6c. This means Bug#21688 is no longer fixed, i.e., Emacs can dump core when aligning Perl code. I'll reopen Bug#21688. Perhaps Stefan or someone else will be able to knock a few cycles free to fix this. I'm afraid I've been spending most of my time elsewhere in Emacs recently, what with the new module code and all.
