error: internal compiler error: unexpected panic
thread 'rustc' panicked at 'arithmetic operation overflowed', /Users/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-mac/build/src/libsyntax/codemap.rs:73

I tried this code:

Compiling github.com/cquinn/meshman @ d2aa1d88cbb8db90778a03092c73fb352c996b39
with cargo build

I expected to see this happen: successful compilation, or error messages.

Instead, this happened: compiler panic.

Thanks for the report. I'm linking this to #23115 which seems to be a similar issue.

This should solve issues #23115, #23469, and #23407.

As the title says, this is just a workaround. The underlying problem is that macro expansion can produce invalid spans. I've opened issue #23480 so we don't forget about that.

Triage: Didn't run the code, but related issue is closed and the commit explicitly mentions fixing this, so this should be closed.
