Compilation of cphalcon fails with gcc-7.2.

[Fisiu]

I'm trying to compile phalcon-3.2.2 with with the latest zephir-0.9.11 using gcc-7.2 however I have some issues. Here is a build log:
phalcon-3.2.2-gcc-7.2.txt

Compilation of zephir didn't return any errors, but cphalcon.

There is no support yet for PHP 7.2. We'll plan to introduce 7.2 support in the Phalcon 4.0.0.

I played around that issue. I build php-zephir-parser, invoked zephir compiler and passed generate option. Once C code has been generated, I tried to compile it and I get errors posted above.

However, if I try to compile extension directly from build/php7/$arch directory → it succeeds.

In both cases I used the same toolchain with gcc 7.2.

Well, as I can see the first version of GCC 7.x was released on May 2, 2017. I did a little research and made sure that most of LTS OS don't use even the 6.x branch. I'm sorry, but I want to close this issue for now. There are several reasons for this:

• This issue is related to Zephir not Phalcon
• It would be rash right now to waste time to solve this (not trivial) problem
• Users always can have multiple versions of the compiler - it is not hard to install one more GCC (for example 5.x)

I'd like to add support for anything/everything at some point, but keeping the issue open doesn't help that. If anyone wants to get started, I'd love that.

Thank you for contributing
