Bug #9038: instance_eval throws RuntimeError for bad syntax (regression from 2.0.0)

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.1.0dev (2013-10-20 trunk 43373) [x86_64-linux]
• Backport: 1.9.3: UNKNOWN, 2.0.0: DONE

[indirect (André Arko)]

In Ruby 2.1.0dev (2013-10-20 trunk 43373), instance_eval throws a RuntimeError when it should throw a SyntaxError, but only the first time it is called. If you use an IRB session to call instance_eval a second time with the exact same arguments, it produces the expected SyntaxError instead of .

Here is an example: ruby -e "instance_eval('/unquoted/string/syntax/error')"

That example raises a SyntaxError on Ruby 2.0.0p247, but raises a RuntimeError on 2.1.0dev (2013-10-20 trunk 43373).

encoding.c: preserve outer errinfo

• encoding.c (load_encoding): should preserve outer errinfo, so that
  expected exception may not be lost. [ruby-core:57949] [Bug #9038]

Even though this issue is not reproducible with 2.0.0, the same flaw exists on ruby_2_0_0. I'll backport r43376 to fix a potential bug.

r43376 is backported to ruby_2_0_0 branch at r43414. I modify test code not to use new assertion of Test::Unit.
