Crash in mix when ca-certificates cannot be parsed #14322
Description
Elixir and Erlang/OTP versions
$ elixir --version
Erlang/OTP 27 [erts-15.2.2] [source] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1] [jit:ns]
Elixir 1.17.3 (compiled with Erlang/OTP 27)
Operating system
Linux (Debian)
Current behavior
I get this noisy error when the system /etc/ssl/certs/ca-certificates.crt cannot be parsed for some reason:
$ mix deps.get

Crash dump is being written to: erl_crash.dump...done
The crash only appears with Elixir >= 1.17 and OTP >= 27. With Elixir 1.16.3 and OTP 27 I get this warning instead:
warning: failed to load system certificates. SSL peer verification will be skipped but downloads are still verified with a checksum
With OTP <= 26 and Elixir 16.x or 17.x mix seems to work despite unparsable /etc/ssl/certs/ca-certificates.crt.
Expected behavior
I would expect Elixir to write an error like "error, cannot parse system CA certificates, aborting", but not to crash noisy like this.
