Hmm, yeah.  A couple of different ways that ltreetest fails without crashing:

https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=seawasp&dt=2021-05-12%2017%3A17%3A15

Otherwise it's mostly free() blowing up, and one case of an assertion
failure in llvm::StringMapImpl::RemoveKey, I guess before free() is
reached:
