It seems there exists reliable reproducer:

$ zypper in php5-phar
$ dd if=/dev/zero of=exploit.tar bs=513 count=1
$ php -r '$tarphar = new PharData("exploit.tar"); $phar =    
          $tarphar->convertToData(Phar::TAR);'
Segmentation fault
$
Comment 4 Petr Gajdos 2015-07-28 08:39:00 UTC 
(tested with 13.2, 12 and 11sp3)
Comment 5 Petr Gajdos 2015-07-28 09:23:05 UTC 
AFTER:

$ php -r '$tarphar = new PharData("exploit.tar"); $phar =    
          $tarphar->convertToData(Phar::TAR);'
PHP Fatal error:  Uncaught exception 'BadMethodCallException' with message 'phar "/exploit.tar" exists and must be unlinked prior to conversion' in Command line code:2
Stack trace:
#0 Command line code(2): PharData->convertToData(2)
