Interestingly, this works fine for me on RHEL8 (with openssl-1.1.1k):

2024-03-07 12:57:53.432 EST [547522] FATAL: F0000: could not load root certificate file "foo.bar": No such file or directory
2024-03-07 12:57:53.432 EST [547522] LOCATION: be_tls_init, be-secure-openssl.c:306

I do reproduce your problem on Fedora 39 with openssl-3.1.1.
So this seems to be a regression on OpenSSL's part. Maybe
they'll figure out how to fix it sometime; that seems to be
another good argument for not pre-empting their error handling.
