Description
I built a stage2 compiler locally using 5b33de3 with parallel-compiler = true. I then tried compiling this code which uses the windows crate using the following cargo invocation: cargo +stage2 rustc -v -- -Z threads=2. This lead to the following error:
thread 'rustc' panicked at 'forcing query with already existing `DepNode`

note: the compiler unexpectedly panicked. this is a bug.

error: could not compile `bindings`
This panic message is similar to the error message in #82991 which also surfaces when cross compiling this code with a non-parallel compiler.
This happens when running with -Z threads=N where N >= 2 (well only tested with 2 and 4).
