Script to reproduce
r247927 has caused a regression where llvm-dis hits an assertion failure when
trying to disassemble bitcode that has been output by the linker:
lib/Bitcode/Reader/BitcodeReader.cpp:4965: std::error_code
{anonymous}::BitcodeReader::findFunctionInStream(llvm::Function*,
llvm::DenseMapBase<llvm::DenseMap<llvm::Function*, long unsigned int>,
llvm::Function*, long unsigned int, llvm::DenseMapInfo<llvm::Function*>,
llvm::detail::DenseMapPair<llvm::Function*, long unsigned int> >::iterator):
Assertion `VSTOffset == 0' failed.
To reproduce place the attached files program.bc and library.bc in the same
directory has link.sh and then execute the link.sh script.
Note that program.bc was generated by LLVM 3.5, and I think library.bc was from
LLVM 3.6.</pre>
