Unlike assertions, these APIs are active at all times. The kernel will treat these errors in the same way as fatal CPU exceptions. Ultimately, the policy of what to do with these errors is implemented in _SysFatalErrorHandler. If the archtecture supports it, a real CPU exception can be triggered which will provide a complete register dump and PC value when the problem occurs. This will provide more helpful information than a fake exception stack frame (_default_esf) passed to the arch-specific exception handling code.
