Description:
------------
I've update phpmyadmin to 2.7.0 and php to 4.4.1 , and the apache crashes with follow logs:
[Mon Dec 05 20:27:22 2005] [notice] child pid 19823 exit signal Segmentation fault (11)
[Mon Dec 05 20:27:23 2005] [notice] child pid 17555 exit signal Segmentation fault (11)
[Mon Dec 05 20:27:24 2005] [notice] child pid 17553 exit signal Segmentation fault (11)
(three times per get sql.php script)
Below of gdb core with php-cli, replace the form values with inserted vars obtain the same error:

Reproduce code:
---------------
phpmyadmin-2.7.0/sql.php , 4.1.15-standard-log , libmysql client version 12.
Expected result:
----------------
In normal situation, the problem happens when browse the data of any table or only invocate sql.php (any SQL statement) with Zero size reply. In fact, i did try to send mailformed SQL sintax (bad sql command or incorrect table/fields name), and the script responses the mailformed sql send, so the problem happens after the SQL validation.
Actual result:
--------------
