           Summary: llvm-link crashes with `Entry == 0 && "Value really did
                    already have handles?"'
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Linker
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: nunoplopes at sapo.pt
                CC: llvmbugs at cs.uiuc.edu


$ llvm-link php_pcre.ll zlib.ll -o a.bc

llvm-link: Value.cpp:449: void llvm::ValueHandleBase::AddToUseList(): Assertion
`Entry == 0 && "Value really did already have handles?"' failed


the input is given in attach. note that if you compile the files first to .bc,
then llvm-link doesn't crash. changing the order of the input files also
"fixes" the problem.
