           Summary: test/ExecutionEngine/test-fp.ll sometimes fails
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Interpreter
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: rspencer at x10sys.com


There's some kind of non-determinism going on with this test case. Sometimes it
passes and sometimes it fails. Attempting to debug it yields a stack like:

(gdb) where
#0  0x00cb40b7 in ?? ()
#1  0x0935d190 in ?? ()
#2  0x00000004 in ?? ()
#3  0x08496fe8 in llvm::ExecutionEngine::runFunctionAsMain (this=0x935d188,
Fn=0x935eea0, argv=@0x881ab3c, envp=0xbf9dbe60)
    at ExecutionEngine.cpp:247
#4  0x0837d5f7 in main (argc=2, argv=0xbf9dbe54, envp=0xbf9dbe60) at lli.cpp:116

But attempting to step through it from ExecutionEngine.cpp allows it to succeed.
I'll try valgrind next.
