Description:
------------
Starting a few days ago (on friday, may 14th i think) my apache under winxp won't start if the gd2, mb_string and exif modules (maybe other too) are activated. Please note that this is recent, and I have not modified the php.ini nor the apache's httpd.conf files (i have also checked for updated in the php.ini-recommanded).

The Apache2 (mine is 2.0.49) won't start and outputs the known apache's pop-up crash window with 'debug' and 'close' and the php.log file inside apache's dir states that:
----
[18-May-2004 13:16:17] PHP Notice:  Constant MB_OVERLOAD_MAIL already defined in Unknown on line 0
----

The Apache1.x (mine is 1.3.31) starts then dies afterwards with a generic crash pop-up window (application error, the memory could not be read .....) and the php.log file has more entries:
----
[18-May-2004 13:10:06] PHP Notice:  Constant MB_OVERLOAD_MAIL already defined in Unknown on line 0
[18-May-2004 13:10:06] PHP Notice:  Constant MB_OVERLOAD_STRING already defined in Unknown on line 0
[18-May-2004 13:10:06] PHP Notice:  Constant MB_OVERLOAD_REGEX already defined in Unknown on line 0
[18-May-2004 13:10:06] PHP Notice:  Constant MB_CASE_UPPER already defined in Unknown on line 0
[18-May-2004 13:10:06] PHP Notice:  Constant MB_CASE_LOWER already defined in Unknown on line 0
[18-May-2004 13:10:06] PHP Notice:  Constant MB_CASE_TITLE already defined in Unknown on line 0
[18-May-2004 13:10:06] PHP Notice:  Constant EXIF_USE_MBSTRING already defined in Unknown on line 0
----

It just seems apache 1.3 goes over more notices than apache2, but still dies when a pae is requested.

The same happens when trying to load the gd2 module, as follows:

Apache2 dies again with an apache's pop-up crash window and php.log has:
----
[18-May-2004 13:22:48] PHP Notice:  Constant IMG_GIF already defined in Unknown on line 0
----

Apache1.x dies when starting thew service/executable as apche2 or later on when a page is requested and php.log has:
----
[18-May-2004 13:25:00] PHP Notice:  Constant IMG_GIF already defined in Unknown on line 0
[18-May-2004 13:25:00] PHP Notice:  Constant IMG_JPG already defined in Unknown on line 0
[18-May-2004 13:25:00] PHP Notice:  Constant IMG_JPEG already defined in Unknown on line 0
....
----
there are 60+ messages of constant IMG_<XXX> already defined .... 

Again apache1 goes over more php notices, but still dies.

Something has surely changed in the latest php5 code causing this sudden reproducible crash ... and i badly needed both gd2 and exif ... 

Thanks for looking into it.
