--- Comment #7 from Martin Jambor <jamborm at gcc dot gnu.org> 2011-01-03 17:40:57 UTC --- The aforementioned patch did not do type comparisons correctly and so only hid the problem. I have already committed a subsequent patch that addresses this (http://gcc.gnu.org/ml/gcc-patches/2010-12/msg01781.html) and the issue resurfaced. I'll go on looking into it tomorrow or on Wednesday.
