Description
LeakSanitizer reports leaks when running t/re/pat.t. (See attached S_regatom-leaks.txt for LS output.)

Same output with non-debugging and debugging builds.

Steps to Reproduce
Build blead using clang-10 and ASan on either Linux or MacOS. (For the latter, explicitly enable LeakSanitizer using ASAN_OPTIONS=detect_leaks=1.)

Expected behavior
No leaks!

Perl configuration
See attached perl-V.txt.

It appears that #18054 is a duplicate of this, and has been fixed.

This issue reported "leaks", has it been verified that the fix in #18054 plugs all of them?
