           Summary: passmanger assertion on -analyze -indvars
           Product: libraries
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core LLVM classes
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: nicholas at mxc.ca


This works on any bytecode:

The backtrace is this:

Program received signal SIGABRT, Aborted.

This is the same assertion as PR1503 but an entirely different backtrace. They
may or may not be the same problem.

Also, "N4llvm23FunctionPassManagerImplE" should be fixed.
