note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

error: the compiler unexpectedly panicked. This is a bug

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.97.0-beta.0 (827651f22 2026-04-23) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type lib -C embed-bitcode=no -C debuginfo=2 -C incremental=[REDACTED]

note: some of the compiler flags provided by cargo are hidden

query stack during panic:
#0 [def_span] looking up span for `action_map::ActionMapExtManual::add_action_entries::{closure#0}`
#1 [typeck_root] type-checking `action_map::ActionMapExtManual::add_action_entries`
#2 [analysis] running analysis passes on crate `gio`
end of query stack

Haven't had the chance to try and reduce this to a minimal example yet. Also attaching files does not appear to work for me, otherwise I would attach the full backtrace; the above is only the first instance of the panic.

I simply built from source with debug = true and debuginfo-level = 2, then used this compiler to build the gio crate.
