It's an extracted version of https://bugs.gentoo.org/718632 where firefox being
built under ccache causes llvm to SIGSEGV.

ccache's hegative caching will be fixed in
https://github.com/ccache/ccache/issues/582. LLVM's behaviour was to SIGSEGVs
when using inconsistent profiling data.

I think it should validate input instead and exit with error.

Also reproducible on LLVM from master. Built llvm master on x86_64-pc-linux-gnu
as:

    $ cmake -DLLVM_ENABLE_PROJECTS='llvm;lld' -DLLVM_BINUTILS_INCDIR=/usr/include -G "Unix Makefiles" ../llvm && make

The crash is:

I also uploaded fully selfcontained example at
https://dev.gentoo.org/~slyfox/bugs/llvm-lto-45636/llvm-lld-crash.tar.gz (40MB!)

Steps to reproduce:

1. clone llvm-project
2. build llvm, lld and LLVMgold as:

   $ cmake -DLLVM_ENABLE_PROJECTS='llvm;lld' -DLLVM_BINUTILS_INCDIR=/usr/include -G "Unix Makefiles" ../llvm

3. tweak path to built llvm in 'bug-master.bash'

   # change to your path
   llvm_root="${HOME}"/dev/git/llvm-project/build/

4. run ./bug-master.bash and get SIGSEGV in #comment1

./bug-master.bash is a raw command to lld:

    cmd=(
    "${llvm_root}"/bin/ld.lld
    --eh-frame-hdr -m elf_x86_64
    -dynamic-linker ./ld-linux-x86-64.so.2
    -o firefox
    ...
    -plugin "${llvm_root}"/lib/LLVMgold.so
    ...
    -plugin-opt=cs-profile-path=./merged.profdata
    ...

All the needed libraries including crt, lib and libstdc++ are in the archive.

The cosmetic "unhandled Error" error handling is fixed in
https://github.com/llvm/llvm-project/commit/09684b08d3b56b8ab0adb8fe46f709aeba29cee6

Actual error handling of bad input is to be fixed:

  Expected<bool> FunctionImporter::importFunctions(
    // ...
    if (Error Err = Mover.move(
            std::move(SrcModule), GlobalsToImport.getArrayRef(),
            [](GlobalValue &, IRMover::ValueAdder) {},
            /*IsPerformingImport=*/true))
      report_fatal_error("Function Import: link error: " +
                         toString(std::move(Err)));

need to figure out why report_fatal_error() is called here.

I guess previous code is not prepared to handle failures and was supposed to
validate the input.
