Thanks. I also installed a minor dfa.c change in Gnulib yesterday to 
pacify Oracle Solaris Studio. No big deal since 'grep' builds OK anyway.

I also ran into a weird issue with test-select on Fedora 37 x86-64. It 
appears to be timing dependent and usually doesn't happen. I can't 
reproduce under strace. This is another Gnulib thing and not relevant to 
grep (other than people might report test failures to bug-grep).

I installed into Gnulib the attached patch which shouldn't hurt but 
which I don't know fixes the bug.
