Ticket #1053 (closed defect: fixed)
php_mapscript code produces warning: dereferencing type-punned pointer will break strict-aliasing rules
|Reported by:||dmorissette||Owned by:||mapserverbugs|
The following zend_hash_find call... pval **phandle; if (zend_hash_find(Z_OBJPROP_P(pThis), "_handle_", sizeof("_handle_"), (void **)&phandle) == SUCCESS) ... results in the following warning: php_mapscript.c:11874: warning: dereferencing type-punned pointer will break strict-aliasing rules I have confirmed that the warning is caused by the (void **)&phandle cast when using -O2 optimization with GCC 3.3. It seems that using (void *)&phandle avoids the warning, I'm just not very clear why. The following thread from the PHP developers list discusses the issue and suggests (void*) as an alternative as well: http://www.zend.com/lists/php-dev/200308/msg00535.html
