           Summary: [4.4 Regression] undeserved uninitialized variable
                    warning regression since 4.4.2
           Product: gcc
           Version: 4.4.5
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: m...@use.net


I have several instances of undeserved uninitialized variable warnings since
upgrading from 4.4.2 to 4.4.5. Oddly, they only seem to come up in 64-bit
targets, but I'm not sure if that's consistent. 

I have attached the pre-processed sources for two examples. One is from
kerberos5 sources.
