Hello,

I'm facing a very odd problem. I'm trying to upgrade a FreeBSD server 
from 10.3-RELEASE to 11.2-RELEASE.
This server has 23 jails, each one running Apache in a different 
context. Some of these jails are running Apache 2.4 with MPM-ITK.

After the upgrade process everything works OK, except for the Apache 
with MPM-ITK:

- Apache crashes with core dump (signal 11) is MPM-ITK is loaded and if 
a configuration exists that uses ITK directives.

- Amache won't crash if no ITK directives are used in its configuration 
files

- Apache won't crash if it's started in foreground with: `httpd -X`, 
then ITK directives works OK.

Versions used before upgrade:

apache24-2.4.29
apr-1.6.3.1.6.1
mod_php56-5.6.32
ap24-mod_mpm_itk-2.4.7_2

Versions used after upgrade:

apache24-2.4.33_1
apr-1.6.3.1.6.1_1
mod_php56-5.6.36_1
ap24-mod_mpm_itk-2.4.7_2

Few more details:

Any idea greatly appreciated.

Thanks,
