Although we don't have absolute proof we have strong evidence to suggest<br>that on recent macOS versions (e.g. 10.13) the first delivery of SIGIO to the<br>VM causes corruption of the code zone if the VM is in or transitioning to<br>machine code. This is similar to crashes seen in the Newspeak VM on linux using<br>the ITIMER heartbeat. There-on the issue was that the dynamic linker would be<br>called within the signal handler on first invocation, and that this would cause<br>the dynamic linker to traverse the Smalltalk JIT code stack, misinteerpret<br>Smalltalk stack frames as ABI-compliant stack frames and cause corruption as<br>a result.<br><br>Since the code is now system wide on Unix, not merely confined to the ITIMER VM,<br>move the sigaltstack initialization to platforms/unix/vm/aio.c and delete the<br>duplications in the ITIMER heartbeat variants.</p>
