aganea added a comment.

Hello @gchatelet! This patches introduces a regression in a two-stage build using rpmalloc on Windows. Bisection lead me here. Would you have a chance to take a look please? Thanks in advance.

To reproduce, I used the following script (rename to make_llvm.bat) F25053901: make_llvm.txt <https://reviews.llvm.org/F25053901>

  C:\git\llvm-project>make_llvm.bat stage1
  ...
  C:\git\llvm-project>ninja clang lld -C stage1
  ...
  C:\git\llvm-project>make_llvm.bat stage2_rpmalloc
  ...
  C:\git\llvm-project>ninja lld -C stage2_rpmalloc

generates:
