loading extension twice results in an error

[jrots]

Hi,
When you run :

$module = phpgo_load("/path/to/example.so", "example");
$module = phpgo_load("/path/to/example.so", "example");

$module->toUpper("foo");

twice and try to call a function you'll get an error :

Uncaught Error: Call to undefined method PHPGo\Module\��Ә��_1_426c601a::toUpper.. 

initializing it once will work ..

I have PHP running "fpm" context so it can happen that a worker gets reused and thus calls phpgo_load again.
Haven't looked to it in detail but think it's something with the cache key of the loaded module in the php extension that goes wrong.

forgot to mention, running: php -v PHP 7.1.8

Kind of dirty fixed it to make it work with only one module for me, i'm not an expert C guy -) (jrots@29fc862)
by disabling the hashmap cache (only keeping a static reference on top in the module)..
so must be something that's changed in the way hashmaps are handled in php 7.1.x

Thank you for writing a nice code for php-go user, arnaud !
I am very appreciated this result but

I have a similar error during testing it:

1. It is good to run phpgo_load at first time in web page
   [Output in page]
   Class [ final class PHPGo\Module\example_0_107063be ] { - Constants [0] { } - Static properties [0] { } - Static methods [0] { } - Properties [0] { } - Methods [2] { Method [ public method takeOverTheWorld ] { - Parameters [0] { } } Method [ public method toUpper ] { - Parameters [1] { Parameter #0 [ $string_0 ] } } } }

2. Refresh page second time ( in a few second after first run )
   Class [ final class PHPGo\Module_2_39b3e97f ] { - Constants [0] { } - Static properties [0] { } - Static methods [0] { } - Properties [0] { } - Methods [0] { } }
   Fatal error: Uncaught Error: Call to undefined method PHPGo\Module_2_39b3e97f::toUpper() in /home/webhost/webhost.dabory.com/phpinfo.php:9 Stack trace: #0 {main} thrown in /home/webhost/webhost.dabory.com/phpinfo.php on line 9
   ==> the module name looks broken and cannot be found.

3. A few minute late, Refreshing the page, I run without error just like 1)

4. The module looks like associated with garbage collection or cleaning memory issue.

Test environment :

1. linux CentOS 7.5 64bit
2. Apache 2.4
3. PHP 7.3

May I get helped about this, Arnaud ?
I am very desparate to implement this functionality.
I can pay money for spending your time if you want to.
