           Summary: ScalarReplAggregates.cpp:474 assert tripped
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gccld
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: scottm at aero.org


ScalarReplAggregates.cpp:474 assert tripped while compiling the gcc4 frontend.
Also occurs when running gccld directly on the resulting bytecode (with -O2 -g
removed and -emit-llvm inserted on the compiler's command line):
