           Summary: Assertion failed in llvm-ld when linking a library
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: llvm-ld
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: zhiruz at gmail.com


My llvm-ld crashed (assertion failure) when I tried to link a bc library.
Will attached the test files later. 

What I did is:

llvm-gcc -c -O0 -emit-llvm libfoo.c -o libfoo.bc
llvm-ar cru libfoo.a libfoo.bc
llvm-ranlib libfoo.a
llvm-gcc -c -O0 -emit-llvm foo.c -o foo.bc

llvm-ld foo.bc libfoo.a -o all.bc 
(and llvm-ld foo.bc -lfoo -o all.bc)

Both produce the following error:

==========================================================================
llvm-ld: /home/llvm/lib/VMCore/Value.cpp:57: virtual llvm::Value::~Value():
