           Summary: Corrupt Stack in SSE Test Failures ?
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Backend: X86
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: rspencer at x10sys.com

Two of the SSE tests fail on Linux with a SEGV. The output is this:

/proj/llvm/llvm/projects/llvm-test/RunSafely.sh 500 /dev/null
Output/sse.stepfft.out-llc Output/sse.stepfft.llc
(no debugging symbols found)
Using host libthread_db library "/lib/libthread_db.so.1".
(no debugging symbols found)
Core was generated by `Output/sse.stepfft.llc'.
Program terminated with signal 11, Segmentation fault.

warning: svr4_current_sos: Can't read pathname for load map: Input/output error

#0  0x0804871e in .BB1_13 ()
#0  0x0804871e in .BB1_13 ()
#1  0x00000000 in ?? ()

Nearly identical results (the stack dump is different) occur for JIT. The JIT
test also produces this:
Previous frame inner to this frame (corrupt stack?)

Possibly the stack is getting corrupted?
