PHP 5.3.26 Seems to have problems compiling template files

I have been successfully using version 2.1.2 on a live website for a long time now, but yesterday I upgraded PHP from version 5.3.23 to 5.3.26 and now the website is having lots of strange problems!



There seems to be several different problems, such as:[list]

[]Connection being reset, clicking on “Try again” sometimes has to be done 3 or 4 times before it works again;

[
]Files being reported as corrupted, even though they are not (requires an Apache reboot!);

[]Complete freeze of the website (requires an Apache reboot!);

[
]Strangely named folders appear in the web root directory, usually containing compiled template files (deleting them does not seem to cause any problems);

[/list]

I have found a reference to a PHP bug in version 5.3.26 which might be related. It then refers to a problem being seen in Prestashop:

  1. [Wed Jul 03 14:59:45 2013] [notice] child pid 6736 exit signal Segmentation fault (11)
  2. zend_mm_heap corrupted

    The 1st error appears about 10 times more than the 2nd error!



    Has anyone else seen these types of problem?

    Has anyone got any suggestion as to where the problem might be in CS-Cart?

    And, more importantly, any ideas as to how this problem can be prevented or fixed?
