Segfault with Apache 2.0.35 and PHP 4.2.0

Hey guys, I've been having consistent problems trying to get PHP working with Apache 2. Basically, after getting everything installed, I try to run apache, and everything seems to work until I realise that no apache tasks are running. Running httpd with a -X gives a segfault. Here's the backtrace: #0 0x4028938c in malloc () from /lib/libc.so.6 #1 0x4028aa93 in calloc () from /lib/libc.so.6 #2 0x403ae58f in zend_hash_init (ht=0x404caa40, nSize=50, pHashFunction=0, pDestructor=0x403ad8b0 <module_destructor>, persistent=1) at zend_hash.c:176 #3 0x403ae620 in zend_hash_init_ex (ht=0x404caa40, nSize=50, pHashFunction=0, pDestructor=0x403ad8b0 <module_destructor>, persistent=1, bApplyProtection=0) at zend_hash.c:197 #4 0x403aa43f in zend_startup (utility_functions=0xbffffc58, extensions=0x0, start_builtin_functions=1) at zend.c:430 #5 0x403b7b05 in php_module_startup (sf=0x404ac1c0) at main.c:902 #6 0x403b5753 in php_apache_server_startup (pconf=0x80b67e0, plog=0x80ee8c0, ptemp=0x8140248, s=0x81428b0) at sapi_apache2.c:442 #7 0x0807cf04 in ap_run_post_config (pconf=0x80b67e0, plog=0x80ee8c0, ptemp=0x8140248, s=0x81428b0) at config.c:129 #8 0x08081da7 in main (argc=2, argv=0xbffffdc4) at main.c:611 #9 0x402346cf in __libc_start_main () from /lib/libc.so.6 This is on a Debian woody system, with the release versions of Apache 2.0.35 and PHP 4.2.0. Anyone got any ideas? Thanks Leigh
