Bug #15760: OpenSSL::BN.new(nil, 2) dumps core
https://bugs.ruby-lang.org/issues/15760#change-77605
* Author: mame (Yusuke Endoh)
* Status: Closed
* Priority: Normal
* Assignee: rhenium (Kazuki Yamaguchi)
* Target version:
* ruby -v: ruby 2.7.0dev (2019-04-10 trunk 67496) [x86_64-linux]
* Backport: 2.4: REQUIRED, 2.5: REQUIRED, 2.6: DONE

ext/openssl/ossl_bn.c
```
221 if (!BN_bin2bn((unsigned char *)StringValuePtr(str), RSTRING_LENINT(str), bn)) {
222 ossl_raise(eBNError, NULL);
223 }
224 break;
```
This code depends on the evaluation order of function arguments. It works if `StringValuePtr(str)` is evaluated earlier than RSTRING_LENINT(str), but it doesn't if the order is reversed, which causes core dump.
