Additional context

I actually failed to build current master c683403 and then run git bisect python x.py check to find first commit that fails to build.

I also tried clear install of Win10 on virtual machine with only python, Visual Studio Build tools and it failed with same error.

It seems to me that the issue is that there are 2 versions of object crate linked

Btw, can we also address the issue that compiler failed to build on one of the Tier 1 platforms for 2 weeks before anybody noticed?

This is likely a duplicate of #142505

FWIW, It seems like the gcc backend doesn't build, not the compiler. Actually, we shouldn't even be checking it on anything else than x64 Linux..

Yes but why nothing checks that steps from beginner contributor guide works?
E.g. clone repo, run python x.py setup, run python x.py check.
