Fwd: Checking cert+key bundle

[Иван Григорьев]

Hello.

I discovered an unusual behavior (imho) - if you “mix” cryptographic
algorithms (ECDSA certificate, RSA key or vice versa), then nginx doesn't
report a problem when reloading and applies the configuration (there are no
errors when executing nginx -t either).

Is this expected behavior or does it look like a bug?

I checked it on different versions and OS, but just in case:
