Unable to find actual suspect through code search and also from the provided CL under regression range, hence adding appropriate label and leaving it as untriaged for more updates on this isuse.

Thanks!

Status: WontFix (was: Untriaged)
Unable to repro. As it's not a security issue and as CachingWordShapeIterator is going away I'll go ahead and mark this as WontFix.
