Using PHP 4.3.9RC3 I keep getting core dumps every time I run php on a
development box, which I'm finding strange.

#0  0x0817ac8e in shutdown_memory_manager (silent=1, clean_cache=0)
at /usr/local/src/php4-STABLE-200409100630/Zend/zend_alloc.c:491
491                                     REMOVE_POINTER_FROM_LIST(ptr);

How does one go around figuring out how to fix this or what is causing
this to core dump?

Looking at the source for zend_alloc.c it contains the following (line
numbering included):

94 #define REMOVE_POINTER_FROM_LIST(p)             \
95     if (p==AG(head)) {                          \
96         AG(head) = p->pNext;                    \
97     } else {                                    \
98         p->pLast->pNext = p->pNext;             \
99     }                                           \
100     if (p->pNext) {                             \
101         p->pNext->pLast = p->pLast;             \
102     }

Provide the full back traces please. Also, does it happen with a
specific script or just always?

You can also try and use valgrind on it. Good chances are that it's not the
memory manager which is causing this problem.
