             Bug #: 54041
           Summary: -mshort ICE in convert_memory_address_addr_space, at
                    explow.c:327
    Classification: Unclassified
           Product: gcc
           Version: 4.7.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ksop@hot.ee


Appears when pointer+index is evaluated, with sizetype being short.

Also tried with one convert_memory_address_addr_space() call commented out, in
which case no ICE is produced. 4.6.3, 4.5.4 affected as well. An -mshort target
makes an interesting testing tool.
