Subject: [Bug c++/43031] [4.5 Regression] internal compiler error: verify_gimple failed after non-trivial conversion error when crosscompiling Firefox
Date: Mon, 15 Feb 2010 22:43:00 -0000	[thread overview]
Message-ID: <20100215224315.12704.qmail@sourceware.org> (raw)

------- Comment #4 from jason at gcc dot gnu dot org  2010-02-15 22:43 -------
Right, the stdcall attribute prevents us from using TYPE_CANONICAL, so it's not
clear to useless_type_conversion that the type of &T::A is the same as P::F. 
Specifically, they are distinct because P::F uses a typedef for L, whereas T::A
does not.

I guess we need to insert an explicit conversion, provide TYPE_CANONICAL even
in the presence of strong attributes, or both.
