Code

The full code in this branch of my fork of quick-xml: https://github.com/Mingun/quick-xml/tree/rustc-ice-2024-06-13

The compiler crashed after I made changes in read_text function in srd/reader/buffered_reader.rs. I tried to reuse introduced read_text_chunk function in implementation of read_text function:
https://github.com/Mingun/quick-xml/blob/171ca07dc2e2e7db38b63055a7b67d28c16c4b64/src/reader/buffered_reader.rs#L51-L69

        #[inline]
        $($async)? fn read_text $(<$lf>)? ( // line 52
            &mut self,
            buf: &'b mut Vec<u8>,
            position: &mut usize,
        ) -> ReadTextResult<'b, &'b mut Vec<u8>> {
            let start = buf.len();
            loop {
                return match self.read_text_chunk(&mut *buf, position) $(.$await)? {
                    ReadTextResult::Markup(_) => return ReadTextResult::Markup(buf),
                    ReadTextResult::UpToMarkup(_) => ReadTextResult::UpToMarkup(&buf[start..]),
                    ReadTextResult::UpToEof(n) if n.is_empty() => ReadTextResult::UpToEof(&buf[start..]),
                    ReadTextResult::UpToEof(_) => continue,

                    ReadTextResult::Err(e) if e.kind() == io::ErrorKind::Interrupted => continue,
                    ReadTextResult::Err(e) => ReadTextResult::Err(e),
                    //_ => todo!() // that line was before the match was finished, I building with it while code was incomplete
                };
            }
        }

When I finish match in loop, compiler crashed. After cargo clean and attempt to reproduce bug it is gone.

Note, that I use Windows 7.

After cargo clean and attempt to reproduce bug it is gone.

Sounds more like an incremental compilation bug than a codegen one?

Also, I'm not sure about the O-windows-7 label... I haven't tried to repro on another platform, but is there any reason to think this is specific to that one?

MCVE would really help.
