cphalcon: Segfaults on user level (syntax) errors

Expected and Actual Behavior

PHP fatal/syntax error.

Describe what you are trying to achieve and what goes wrong.

From any controller, trying to call simple facade method defined in ControllerBase or wherever, making a mistake which should cause only syntax error. Instead, nginx throws 502 Bad Gateway HTTP response, while PHP-FPM throws: [480094.083490] php-fpm7.0[30488]: segfault at 1c ip 00005563990e8d28 sp 00007ffdf56be410 error 4 in php-fpm7.0[556398e93000+3a9000]

Backtrace:

Provide minimal script to reproduce the issue

var_dump(
            $this->auth('   contact@my(site).com', '        mytestpass123'),
        );

(if I remove syntax error - comma sign at the end of the statement, stack works fine)

This can happen anytime developer will omit closing } or comma sign. Those are user level errors and should not crash application server. 😕
