When I try to run ./x.py doc with compiler-docs = true in config.toml, I get several errors. I started discussing this on Zulip. I am trying this on latest master and a clean build/ directory.
First I got errors related to -Znormalize-docs. #79954 fixed those.
Then I got a 'Unable to resolve external crate proc_macro2' panic. #79984 fixed that.
Finally I got this (even after clearing build/):
error[E0460]: found possibly newer version of crate `std` which `synstructure` depends on
--> compiler/rustc_macros/src/lib.rs:5:5

5 | use synstructure::decl_derive;
| ^^^^^^^^^^^^

= note: perhaps that crate needs to be recompiled?
= note: the following crate versions were found:
crate `std`: /home/nadrieril/wip/forks/rust/build/x86_64-unknown-linux-gnu/stage0-sysroot/lib/rustlib/x86_64-unknown-linux-gnu/lib/libstd

crate `std`: /home/nadrieril/wip/forks/rust/build/x86_64-unknown-linux-gnu/stage0-sysroot/lib/rustlib/x86_64-unknown-linux-gnu/lib/libstd

crate `synstructure`: /home/nadrieril/wip/forks/rust/build/x86_64-unknown-linux-gnu/stage0-rustc/release/deps/libsynstructure-3b73f5ee64fee340.rmeta
error: aborting due to previous error
error: could not document `rustc_macros`
And at that point I thought I'd open an issue because I have no idea what's happening.
EDIT: that error is the same as was found in #74976, which seemed to have vanished spontaneously(?).
EDIT: here's my config.toml without the comments:
changelog-seen = 2
[llvm]
download-ci-llvm = true
assertions = true
[build]
compiler-docs = true
[rust]
debug-logging = true
debuginfo-level-rustc = 1
incremental = true
deny-warnings = falseEDIT: tried with incremental = false and got the same error
