           Summary: setOperand() out of range!
           Product: tools
           Version: 1.5
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gccas
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: bryan.turner at pobox.com


LLVM 1.5, patched with recent bug fixes (577-582).

Bugpoint tracked it down to func_31585107l().  I have not reduced input source
code under the assumption that the bugpoint file will be more usefull.  Let me
know if a source code reduction is necessary.

Attachments:
- Original source file
- Intermediate file from -save-temps
- bugpoint reduced case
