zltime::reportPerf returns null in production, causes attempt to access NULL as array

[Miguel-Serejo]

When zl_mode is set to prod with default configs (debugLog=false and debugLogOnFault=false), the debugger will call $temp = ztime::reportPerf(memory_get_usage() - $zl_debugMem);, which will return null, and then attempt to access $temp['report'] and $temp['time']

This causes two warnings to trigger on every page load:
Warning: Trying to access array offset on null in zerolith/classes/zl.php on line 676
Warning: Trying to access array offset on null in zerolith/classes/zl.php on line 677

Only userland "fix" currently is to change zl_mode to something other than prod.
