And if you knew what you were doing, what would you do? Is this problem being discussed anywhere? I might be able to help.
Not really. I played a little with the developer preview but other priorities interfered. Essentially you'll have to debug it and figure out what's wrong with the signal handling.
signal_init_process is called, and the disassembly looks right: it seems to be calling sigaction with the the correct pointer to segv_handler. However, segv_handler is not called when the signal is received. I'll keep investigating.
