[Bug tree-optimization/27087] [4.1/4.2 regression] ICE in merge_alias_info
------- Comment #3 from law at redhat dot com 2006-04-11 05:41 -------
The problem is that may_propagate_copy and merge_alias_info are inconsistent.
ie, DOM properly calls may_propagate_copy to determine if a particular copy
propagation is valid. may_propagate_copy returns true indicating the copy
propagation is valid. However, when the copy propagation is performed and we
reach merge_alias_info, merge_alias_info has an additional sanity check that
causes it to fail.
This really isn't a DOM problem.
