           Summary: gccld crashes on assertion
           Product: tools
           Version: 1.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gccld
        AssignedTo: criswell at uiuc.edu
        ReportedBy: criswell at uiuc.edu


The gccld program dies when attempting to link the bytecode file below.  The
command line and assertion reads as follows (I believe the puts error is innocuous):

gccld -o test2
-L/home/vadve/lattner/local/x86/llvm-gcc/bin/../lib/gcc/i686-pc-linux-gnu/3.4-llvm
-L/home/vadve/lattner/local/x86/llvm-gcc/bin/../lib/gcc
