Segmentation fault with the PHP SDK

I just tried to install the PHP SDK on my Ubuntu 14.04.
I started with the C SDK, then isntalled the PHP SDK with pecl.
Every works fine, i got no errors, a is installed in /usr/lib/php55/…

But when i add a to my php.ini everything broke, i can’t display any php page.

I checked the logs and see:

[Wed Jan 20 11:36:39.872396 2016] [core:notice] [pid 4265] AH00052: child pid 4298 exit signal Segmentation fault (11)

Looks bad uh ?

Any tips to make this works?
