Segfault when adding custom function to Volt

[michalderlatka]

I'm using Phalcon 1.3.3 on Nginx, PHP 5.5.17 with Xdebug 2.2.5. When using custom function in Volt's template, php-fpm crashes. It seems this problem is related with xdebug, because after disabling xdebug extension, fpm is not crashing anymore.

in bootstrap file:

$volt->getCompiler()->addFunction('_', function ($resolvedArgs, $exprArgs) use ($di) {
return sprintf('('%s')', $exprArgs[0]['expr']['value']);
});

template:

{{ _("Test") }}

gdb:

Program terminated with signal 11, Segmentation fault.

This is caused because of Xdebug
