Description
Coming here from rust-lang/rust-clippy#12414.
I found a very specific macro that causes the Rust compiler to hang infinitely while doing cargo check and consumes increasingly more memory over time, going into the 100s of gigabytes sometimes (it is put in swap then of course). This already caused my computer to crash multiple times...
fn main() {
macro_rules! handle {
($($tt:tt)*) => {
handle! {
@@internal
done: [$($tt)*],
$($tt:tt)*
}
};
(
@@internal
done: [$($done:tt)*],
$method:ident Request: $req:ident($req_ty:ty) -> $res_ty:ty;
$($rest:tt)*
) => {
}
}
handle! {
"initialize" Request: initialize(InitializeParams) -> InitializeResult;
}
}The problematic function is most likely rustc_expand::mbe::transcribe::transcribe.
A related issue is #95698, where the compiler also hangs during macro expansion.
