gcc/rust/ChangeLog:

* resolve/rust-late-name-resolver-2.0.cc (Late::visit): Add error emitting

From issue #2876 , I clone gcc locally, then run from build dir

 ../gcc_src/configure '--with-pkgversion=basepoints/gcc-14-9118-g3232ebd91ed, built at 1708915534' --prefix=/tmp/gcc-x86_64-linux --enable-werror-always --enable-languages=rust --disable-gcov --disable-shared --disable-threads --target=x86_64-linux --without-headers --disable-multilib

to verify the crash.

Then i edit in-place of the recently cloned gcc the file rust-late-name-resolver-2.0.cc until the problem regarding the file goes away after rebuilding. The rest of the errors are in gcc error itself

I then transfer the newly edited portion to the gccrs codebase

+      return;

that looks great - for style issues, could you also add braces to the above if and else if statements? this way the else one isn't the only one with braces and it looks more uniform.

yes, i'll get on it soon

I mistyped cp ./contrib/clang-format ./clang-format instead of cp ./contrib/clang-format ./.clang-format on the src folder. Was wondering why it can't catch these formatting errors locally

I fetched master from upstream and then rebase onto my branch so that the content matched this repository's master, not sure if there's any other way to have github not show false information that I actually modified 62 files???

it's showing me 1 file changed, so I think everything's good :) sometimes after a rebase the github frontend lags behind and takes a while to update. the commit list can also get messed up

thanks for taking care of this :) LGTM!
