Code

macro_rules! make_macro {
    ($macro_name:tt $($matcher:tt)*) => {
        #[macro_export]
        macro_rules! $macro_name [T; 0]
    }
}
make_macro! {
    (<= $($matcher)* =>) => {};
}

Error output

The problem seems to be this:

error: macros that expand to items must be delimited with braces or followed by a semicolon (note how the `r` is green)
 --> 92998.rs:4:22
  |
4 |         macro_rules! $macro_name [T; 0]
  |                      ^^^^^^^^^^^
  |
help: change the delimiters to curly braces
  |
4 |         macro_rules! {} [T; 0]
  |                      ~
help: add a semicolon
  |
4 |         macro_rules! $macro_name; [T; 0]
  |                                 +

But it looks like rustc already gets the span wrong:

This appears to stem from the span for the delimited block being changed here. I will work on a fix now and submit it.

Rollup merge of rust-lang#118928 - EliseZeroTwo:EliseZeroTwo/fix-issue-118786, r=cjgillot

fix: Overlapping spans in delimited meta-vars

Closes rust-lang#118786

Delimited meta-vars inside of MBE's spans were set to have the same opening and closing position resulting in an ICE when debug assertions were enabled and an error was present in the templated code.

This ensures that the spans do not overlap, whilst still having the spans point at the usage of the meta-var inside the macro definition.

It includes a regression test.
