Subject: [ruby-core:57082] [ruby-trunk - Bug #8880] Refinements bug in ruby	2.1.0dev (2013-09-08) [x86_64-linux]


Issue #8880 has been updated by nobu (Nobuyoshi Nakada).


#8722 is irrelevant, and it occurs regardless of eval.

Seems refined method definition doesn't increase seq in the class.

Hi,

I found a bug in the refinements implementation of Ruby 2.1.0. It is related to https://bugs.ruby-lang.org/issues/8722. On ruby 2.0.0p0 (2013-02-24 revision 39474) this does not occur.

The VM segfaults when the attached code is executed. The problem is that a used refinement is modified afterwards.

Daniel
