### Description

I set some configuration parameters in the global section of kamailio.cfg and wanted to read them later in request_route and reply_route. But when accessing them, Kamailio segfaults.

However, I can read them via kamcmd after startup.

### Troubleshooting

#### Reproduction

Set the following config parameter in your kamailio.cfg in the global section: ``` config.foo = "hello Daniel" ```

later, put your request and reply route in the configuration file:

``` request_route { xlog("L_INFO", "Reading config.foo into variable"); $var(configfoo) = $sel(cfg_get.config.foo); }

onreply_route { xlog("L_INFO", "Reading config.foo into variable"); $var(configfoo) = $sel(cfg_get.config.foo); } ```
