#159401 gates this test with min GDB 15.1 that I can't reproduce the failure locally with. CI as of time of writing typically uses GDB 12.1 under Ubuntu 22.04, so the min GDB gate kicks it out of CI but still lets it run locally with GDB >= 15.1.

See investigation at: #t-compiler > `tests/debuginfo/function-call.rs` + gdb recently flaky @ 💬
It's quite likely that the gdb version 12.1 we use in CI doesn't support the hardware of the CI runners (well), i.e. processors
which are released later than gdb 12.1.
