Nut sure whether this is an issue or not but I see it a lot while
 compiling master:

   Zend/zend_alloc.h:57:236: warning: unknown attribute 'alloc_size'
   ignored [-Wunknown-attributes]
   __attribute__ ((visibility("default"))) void* _emalloc(size_t size,
   const char *__zend_filename, const uint __zend_lineno,
   const char *__zend_orig_filename, const uint __zend_orig_lineno)
   __attribute__ ((__malloc__)) __attribute__ ((alloc_size(1)));

   Zend/zend_alloc.h:61:250: warning: unknown attribute 'alloc_size'
   ignored [-Wunknown-attributes]
   __attribute__ ((visibility("default"))) void* _ecalloc(size_t nmemb,
   size_t size , const char *__zend_filename, const uint __zend_lineno,
   const char *__zend_orig_filename, const uint __zend_orig_lineno)
   __attribute__ ((__malloc__)) __attribute__ ((alloc_size(1,2)));

   Zend/zend_alloc.h:62:238: warning: unknown attribute 'alloc_size'
