Hi @mizvekov.

This change has caused a failure in Clang's stage 2 CI on the green dragon Darwin CI: https://green.lab.llvm.org/green/job/clang-stage2-Rthinlto/6390/console.

  Assertion failed: (lvaluePath->getType() == elemTy && "Unexpected type reference!"), function readAPValue, file /Users/buildslave/jenkins/workspace/clang-stage1-RA/clang-build/tools/clang/include/clang/AST/AbstractBasicReader.inc, line 736.
  Assertion failed: (BlockScope.empty() && CurAbbrevs.empty() && "Block imbalance"), function ~BitstreamWriter, file /Users/buildslave/jenkins/workspace/clang-stage1-RA/llvm-project/llvm/include/llvm/Bitstream/BitstreamWriter.h, line 119.

Full log is here - https://green.lab.llvm.org/green/job/clang-stage2-Rthinlto/6390/console.

This happens when a Release+Asserts stage 1 clang is building stage 2 clang when Clang modules are enabled. You should be able to reproduce this by building Release+Asserts clang, and then using it to build clang again with the LLVM_ENABLE_MODULES cmake option.

Could you please look into this as soon as you can?
