==9380== Final error counts will be inaccurate.  Go fix your program!
==9380== Rerun with --error-limit=no to disable this cutoff.  Note
==9380== that errors may occur in your program without prior warning from
==9380== Valgrind, because errors are no longer being displayed.

> When loading the xml documentation the asterisk always dies with an segmentation fault. Although this should not influence each other, this only happens when the /etc/asterisk/asterisk.conf has an include to an another file. 
> - When the include in the asterisk.conf is removed the xml documentation is loaded perfectly fine. No segfault.
> - When the xml documentation is remove the include in the asterisk.conf works perfectly fine. No segfault.
> - The segfault always appears (100% reproducible.) when both is used.
