; Linking these two translation units causes there to be two LLVM values in the
; symbol table with the same name and same type.  When this occurs, the symbol
; table class is DROPPING one of the values, instead of renaming it like a nice
; little symbol table.  This is causing llvm-link to die, at no fault of its
; own.
