------- Comment #4 from victork at gcc dot gnu dot org 2007-10-09 06:52 -------
The problem starts when dependence checker fails to find distance vector
for a known dependence. I've opened another missed-optimization PR33707.
The vectorizer continue by means of versioning for alias. I'm still looking,
why this eventually caused the ICE.
Accepting the bug.
