FWIW, other SAPI's don't appear to raise a warning and a lot of people make warnings exceptions. But yeah, I agree and that's the entire purpose of the discussion on internals....
For now, it is probably better to conform to existing behavior vs. introducing new behavior.

I agree. On a second look, this is just making zend-max-execution-timers consistent with other timeout implementations. set_time_limit(-1) disables the timeout (probably by accident), and people rely on it: https://github.com/search?q=%22set_time_limit%28-1%29%22&type=code.

Calling
set_time_limit()or settingmax_execution_timeto a negative value or to a value superior to 999,999,999 can trigger C errors: php/frankenphp#713 / https://linux.die.net/man/2/setitimerThis patch normalizes such values as 0.
@withinboredom raised the issue on https://externals.io/message/123108, and we may indeed correctly specify this behavior, but in the meantime, we should at least not throw a C error, which is inconsistent with what is done on other platforms.
