Description:
------------
Similar to bug #51216, a PHP build with "--with-xsl" unexpectedly ends with the intermediately build "sapi/cli/php" crashing with a segmentation fault when called in the "Generating phar.php" build step. The environment is:

AIX: 6100-08-01-1245
xlC: 11.01.0000.0009
php: 5.3.26
libxml2: 2.9.1
libxslt: 1.1.28

Disabling "--with-xsl" produces a successful PHP build though.

Test script:
---------------
Build PHP with the above platform/versions and the "--with-xsl" configure option.

Expected result:
----------------
Successful PHP build

Actual result:
--------------
$ dbx sapi/cli/php core 
Type 'help' for help.
