Follow-up Comment #4, bug #65468 (group octave):
Indeed, the same error occurs when I rebuild 8.4.0 against the current
toolchain.
When using __debug_octave__ I get
marius@Mira ~ % lldb -p 69398
(lldb) process attach --pid 69398
Process 69398 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = signal SIGSTOP

As I had suspected, the issue seems to be libunwind.
