ICE: no warnings or errors encountered even though `delayed_good_path_bugs` issued

[feds01]

Sporadic ICE when compiling a crate occurred, I could not reproduce this issue after the initial occurrence.

This seems like an incremental compilation issue

This seems like an incremental compilation issue

For the record I'm seeing something like this in my CI setup which builds from scratch:

error: internal compiler error: no warnings or errors encountered even though `delayed_good_path_bugs` issued

error: internal compiler error: trimmed_def_paths constructed but no error emitted; use `DelayDm` for lints or `with_no_trimmed_paths` for debugging

And the info is:

note: the compiler unexpectedly panicked. this is a bug.

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

Context is I've added matrix builds to check stable, beta and nightly and on beta it fails while it works on both stable and nightly. (I've ran the CI setup twice and it failed twice).

Attached you'll find the build log and if this helps here's a link to the CI pipelines: https://ci.codeberg.org/wiktor/pysequoia/pipeline/97

This seems to be the same as #106800 and #108155 which was closed as fixed, but since 1.68 the openpgp-card project is also reporting this issue happening.
