New Revision: 178871

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=178871
Log:

This patch fixes two bugs which cause an internal compiler error in
annotalysis. The first change fixes a failure when a variable is
typecast from an unknown (forward-defined)  type.  The second change
fixes a case in which an assert was triggered, because subexpressions
were not canonicalized correctly.
