The failing test is subclass::async_initable::tests::test_async_initable_new_failure

It is *supposed* to panic, so there's a high probability the issue is in rustc rather than in rust-gio.

I have investigated this issue and determined this is a rust-glib (note, not rustc or rust-gio) issue which has been fixed upstream.

It looked like a rustc/Rust std bug because the FFI wrapper inside rust-gio corrupted the stack so severely that libunwind could not call the clean-up function (it returned URC_FAILURE and transferred control back to the program). The Rust std panic handler did not expect this to happen (unwind clean-up will terminate the program, it should not return when the unwinding succeeds).

This only happened on armhf because URC_FAILURE is ARM-specific (and when using EHABI, see
Chapter 8 in https://github.com/ARM-software/abi-aa/releases/download/2021Q1/ehabi32.pdf).

I will submit a backported patch in a moment.
