- Organization: Red Hat Canada
Fixes a latent bug we've had since February. It just now
triggered on PPC (no wonder PPC has been so flakey). Jeff, I
guess you meant pushing a wide int here, eh? :)
Will commit after testing this week's merge on ppc and amd64.
Diego.
* tree-dfa.c (add_referenced_var): Fix type of element
pushed into aliased_objects_alias_set.
