--- Comment #3 from Ira Rosen <irar at il dot ibm.com> 2011-04-27 10:25:16 UTC ---
As analyzed by Richard, the problem (btw, unrelated to Richard's patch) is that
the vectorization factor is changed after the analysis for this loop, and the
same checks that worked fine during the analysis, now fail during the
transformation.

I'll try to move the vectorization factor calculation before the statements
analysis to avoid this. 

Ira
