Bug #5972: OpenSSL::ASN1::GeneralString - double INT2NUM() results in invalid ASN.1 tag
https://bugs.ruby-lang.org/issues/5972

Author: Mantas Mikulト溶as
Status: Open
Priority: Normal
Assignee: Martin Bosslet
Category: ext
Target version: 2.0.0
ruby -v: ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]


In ext/openssl/ossl_asn1.c, INT2NUM() is being called twice for V_ASN1_GENERALSTRING:

 rb_hash_aset(class_tag_map, cASN1GeneralString, INT2NUM(INT2NUM(V_ASN1_GENERALSTRING)));

This causes OpenSSL::ASN1::GeneralString.new to return "unsupported ASN.1 type":

 $ irb -ropenssl
 irb > OpenSSL::ASN1::GeneralString.new("foo").to_der
 OpenSSL::ASN1::ASN1Error: unsupported ASN.1 type
 	from (irb):1:in `to_der'
 	from (irb):1
 	from /usr/bin/irb:12:in `<main>'
 irb > 

Expected result:

 $ irb -ropenssl
 irb > OpenSSL::ASN1::GeneralString.new("foo").to_der
 => "\e\x03foo"
 irb > 

Patch attached.
