Compliance-Tests: tb_garbage_collection.all failed to suspend thread

[yikkrubz]

The Compliance-Tests testsuite does no longer finish. Running the tb_garbage_collection testbench causes the testsuite to hang. The error message is: Fatal: 0ms+0: failed to suspend thread 1 (268435459)

Please report this bug at https://github.com/nickg/nvc/issues

When I configure nvc with --disable-lto and --enable-debug, the test run completes. This time running tb_garbage_collection causes Assertion failed: (thread->port != MACH_PORT_NULL), function stop_world, file thread.c, line 1329, followed by a SIGABRT (see below).

I can reproduce this on Arm-based macOS 14.5 too. Do you know if this test has ever passed on macOS? I don't think that code has changed for several releases.

When I ran the compliance tests before last time, I recorded the failing tests (see below). It seems the tb_garbage_collection.all test passed.
I am sorry I did not note the date when I ran the tests. I assume the test was working on Sep 24, 2023 when I filed an issue (Compliance-tests).

Thank you very much for fixing this issue.
