------- Comment #3 from george at gcc dot gnu dot org 2009-09-16 04:49 -------
Additional investigation reveals that the ICE is triggered by OpenMP
conformance violation. There is a go to out of the body of an OMP parallel
region. Commenting out line 1105 of xrotate.f suppresses the ICE and leads to
successful compilation with -fopenmp.

D.1404 isn't defined anywhere. Also I didn't see diagnose_sb_2 handle
