------- Comment #1 from rguenth at gcc dot gnu dot org 2006-03-24 10:30 -------
Confirmed. We ICE after IVOPTs during computation of dominance frontiers.
Other than that, tree-loop-linear seems to be somewhat buggy in general.
Program received signal SIGSEGV, Segmentation fault.

I'd say it hints at a broken CFG.
