The new manager's "configure" has no "--disable-zend-memory-manager" option, but it has "--enable-malloc-mm" instead. It is enabled by default in DEBUG build and disabled by default in RELEASE built. It allows select malloc/emalloc at runtime. So you can use internal and external memory debuggers without recompilation. $ sapi/cli/php -r 'leak();' $ USE_ZEND_ALLOC=0 valgrind --leak-check=full -r 'leak();' The patch allows tweaking memory manager with ZEND_MM_MEM_TYPE and ZEND_MM_SEG_SIZE environment variables. Default values are "malloc" and "256K". Dependent on target system you can also use "mmap_anon", "mmap_zero" and "win32" storage managers. $ ZEND_MM_MEM_TYPE=mmap_anon ZEND_MM_SEG_SIZE=1M sapi/cli/php
