Hi, wasmtime testsuite found a deadlock in qemu_plugin_user_exit(). I tracked it down to one of my earlier patches, which introduced cleanup in dump_core_and_abort().
Patch 1 fixes the issue, patches 2 and 3 fix __builtin_trap() handling in microblaze and sparc - which is needed for patch 4, that adds a test. Just before sending this, I noticed that a solution has already been proposed in [1], but apparently it wasn't accepted.
