Ivan pushed a "generic" implementation using signal handlers, so no inline asm needed. In my quick test so far, this seems to solve the crashes that I am able to reproduce even without the workaround I put in place for 2.23.13. There's a "scary" warning message, but worst case we can patch that away.
