Confirmed. Something must have broken since the last patch revision. I'll see if I can figure out / fix this soon.

@luismarques
I have tried the patch with llvm12, test case is provide by jade(https://gist.github.com/e2efac2f780ed820277dbaf608805f4e), but it didn't worked for me.
After execute 'gdb-remote 1234', the terminal shows:

Process 1 stopped
* Thread #1, stop reason = signal SIGTRAP
       frame #0: 0xffffffffffffffff
}

It seems that the unwind didn't succeed, can you figure out the problem?
my qemu vesion: 4.2.1
Thanks.
