gmap demo : Fatal error: Object expected as argument. in /home/ii/mapserver/gmap/htdocs/gmap75.php3 on line 696

This is a follow-up on a bug with MapScript with PHP4.0.4 that was
posted a few weeks ago:

There was indeed a bug that will cause random instability in MapScript
v3.4 compiled with PHP 4 ... the fix will be part of the next 3.5
release, but I have seen a few messages on the list about odd behaviors
with PHP4 MapScript and while I'm not 100% sure I suspect that some of
them may be related to this.

So if you are running PHP4/MapScript with v3.4 and noticed intermittent
crashes or the above error message, then it might be a good idea to
patch your php_mapscript.so.  (Note that this bug was for PHP4 only...
PHP3 is fine)

The fix is to add a ZVAL_ADDREF() call at the end of the PHP4 version of
_phpms_add_property_object() in php_mapscript_util.c, around line 545:

    *(*phandle) = *pObjToAdd;
    ZVAL_ADDREF(*phandle);

    return 0;
