This one also seems to crash only when (one of) MPM threaded mode(s) is in use
right? Looking at the trace it's in event MPM threaded mode and also uses
PCRE(1) and not PCRE2 yet - already present in 2.4.53 but by default I only saw
it to be in future Ubuntu packages.

And possibly it is not failing in MPM prefork mode?

Additionaly, possibly checking this pattern with pcretest (even matching exact
libpcre version used with your httpd) against the paths you were testing with
might not show problems - if so, it might mean a threading-related change
between 2.4.52 and 2.4.53 could be causing it really (even though segfault is
thrown from within libpcre)?
