dist-x86_64-freebsd fails when building with debug assertions

[Aaron1011]

Steps to reproduce:

1. Run src/ci/docker/run.sh dist-x86_64-freebsd (note that DEPLOY=1 is not set, which is why we don't see this on Azure)
2. Observe the following ICE (full log):

This appears to be a legimitate bug, which is normally not exposed due to the if cfg!(debug_assertions) block in validate_hir_id_for_typeck_tables not running on CI.

Possibly related to #57298

Does not seem to be specific to FreeBSD: #63861
