--- Comment #2 from Mikael Pettersson <mikpe at it dot uu.se> 2011-06-19 14:02:27 UTC --- Created attachment 24559 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24559 preprocessed test case Several files in gsoc2010-fftw-neon ICE gcc-4.4 in change_address_1, this is the preprocessed code for the first one. The ICE doesn't occur with gcc-4.6.0, it was cured by r159480, a generic patch to reduce stack frame sizes. The description <http://gcc.gnu.org/ml/gcc-patches/2010-05/msg00441.html> didn't mention fixing any bugs, so I don't know if it actually fixed this bug or just made it latent.
