[Pkg-php-pecl] Bug#820666: php5-redis: Segfault on pear upgrade-all with php5-redis installed

[root]

Package: php5-redis
Version: 2.2.5-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

To reproduce the bug I started with fress jessie 64 install in a VirtualBox

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

In the fresh install I issued these commands:

sudo -i
apt-get update && apt-get -y dist-upgrade
apt-get install php5 php5-redis php-pear php5-dev
pear update-channels
pear upgrade-all

   * What was the outcome of this action?

The last line of the output was "Segmentetion falut".

   * What outcome did you expect instead?

I do not expect segmentation falut for these commands.
