The issue is non-deterministically triggered in contrib checks, either in
int or ltree, but not elsewhere. This suggests issues specific to these
modules, or triggered by these modules. Hmmm…
Hmm, yeah. A couple of different ways that ltreetest fails without crashing:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=seawasp&dt=2021-05-13%2001%3A17%3A15
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:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=seawasp&dt=2021-05-14%2009%3A17%3A15
It seems that the upload of the valgrind run (many hours…) failed on "413
request entity too large", and everything seems to have been cleaned
despite the "--keepall" I think I put when I started the run.
Not sure about the best way to proceed.
