----------------------------------------
Bug #19828: Segfault when `OpenSSL::X509::Certificate#public_key=` is given a `OpenSS::PKey::DH` object
https://bugs.ruby-lang.org/issues/19828

* Author: postmodern (Hal Brodigan)
* Status: Open
* Priority: Normal
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN
----------------------------------------
The OpenSSL bindings cause a SegFault when creating a new OpenSSL::X509::Certificate object and setting it's `public_key` to the `public_key` of a new `OpenSSL::PKey::DH` key-pair.

### Steps To Reproduce

```ruby
#!/usr/bin/env ruby

require 'openssl'

cert = OpenSSL::X509::Certificate.new
key  = OpenSSL::PKey::DH.generate(1024)

cert.public_key = key.public_key
```

### Expected Results

Sets the public key.

### Actual Results

```
