           Summary: Function is declared defined and undefined after link
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gccld
        AssignedTo: criswell at uiuc.edu
        ReportedBy: criswell at uiuc.edu


When compiling and linking the lshaped program (part of ATR), the symbol
_ZNK18OsiSolverInterface20getFractionalIndicesEd is defined twice in the
resulting bytecode file: once as an undefined symbol and once as a defined local
function (according to llvm-nm).

This causes the JIT problems; the first time it looks for the function, it
thinks it is external and attmepts to find it in the JIT's address space.  Later
on, the JIT finds the function definition and uses it properly.

I'm guessing this behavior is from the libraries used by gccld.
