Description:
------------
I am using the version of PHP from Ubuntu 11.11 and have the following array 
which causes sort to crash.  The output below was produced with print_r just 
before the call to the sort.

Sorry I cannot upgrade because there is no newer version available yet for ubuntu 
if I do 'apt-get upgrade'  

I do this call : sort($array, SORT_STRING);

If I change it to this, it works :


usort($array, strcasecmp);

Version 5.3.6-13ubuntu3.5

Test script:
---------------
(
    [0] => SeqFeature Object
        (
            [fType] => origin of replication
            [fValue] => F1
            [fStart] => 138
            [fEnd] => 444
            [fDir] => reverse                [fDescr] =>
            [description] =>                [isFeature] => 1
            [featureID] => -1
            [pName] =>                [pAlias] =>
            [pDescr] =>
            [pCategory] =>                [pValue] =>
            [propID] =>            )

    [1] => SeqFeature Object
        (
            [fType] => origin of replication
            [fValue] => pUC
            [fStart] => 1231
            [fEnd] => 1850
            [fDir] => reverse
            [fDescr] =>
            [description] =>
            [isFeature] => 1                [featureID] => -1
            [pName] =>
            [pAlias] =>
            [pDescr] =>
            [pCategory] =>
            [pValue] =>
            [propID] =>
        )

)

Expected result:
----------------
Have the array sorted

Actual result:
--------------
Sort never returns
