.ll that doesn't assemble

The attached LLVM assembler was produced by running
llvm-gcc on unwind-dw2.c in the gcc sources with
options -S -emit-llvm, at -O0.  However trying to
assemble it with llvm-as gives

llvm-as unwind-dw2.ll
llvm-as: unwind-dw2.ll:5660,0: Unresolved global references exist:
  i32 (i32) * __gthrw_pthread_cancel

Checking by hand shows that everything is dandy, so
this seems to be an llvm-as bug.
