Bug #2243: Segfault when a PHP file virtual()s another

From: Ken.Coar@Golux.COm Operating system: RH5.2 Linux 2.0.36 PHP version: 3.0 Latest CVS (06/09/1999) PHP Bug Type: Reproduceable crash Bug description: Segfault when a PHP file virtual()s another PHP 3.0.13-dev, Apache 1.3.10-dev, MySQL support configured. If a PHP file uses virtual() to include another via a subrequest, it will either throw an error ('Cannot include a PHP file') or else segfault. (The behaviour depends upon how PHP file recognition is configured; I have a fix.) Here is a backtrace from the core file: #0 0x400a778d in __libc_free (mem=0x80d3438) at malloc.c:2861 #1 0x40292cbd in _efree (ptr=0x80d3448) at alloc.c:173 #2 0x4028d1b6 in _php3_hash_destroy (ht=0x40307980) at php3_hash.c:683 #3 0x402cacaa in phpparse () at control_structures_inline.h:956 #4 0x4028c012 in php3_parse (yyin=0x80c93b8) at main.c:1554 #5 0x4028c2f0 in apache_php3_module_main (r=0x80c6c14, fd=32, display_source_mode=0, preprocessed=0) at main.c:1935 #6 0x4028961f in send_php3 (r=0x80c6c14, display_source_mode=0, preprocessed=0, filename=0x80c76a4 "/home/coar/web/served/virtual1.phtml") at ./mod_php3.c:245 #7 0x40289686 in send_parsed_php3 (r=0x80c6c14) at ./mod_php3.c:261 #8 0x8051bba in ap_invoke_handler (r=0x80c6c14) at http_config.c:508 #9 0x805edb1 in process_request_internal (r=0x80c6c14) at http_request.c:1214 #10 0x805edff in ap_process_request (r=0x80c6c14) at http_request.c:1230 #11 0x8059238 in child_main (child_num_arg=0) at http_main.c:4035 #12 0x80593ee in make_child (s=0x8091db4, slot=0, now=936594966) at http_main.c:4194 #13 0x805945b in startup_children (number_to_start=5) at http_main.c:4221 #14 0x80598f6 in standalone_main (argc=1, argv=0xbffffcb0) at http_main.c:4509 #15 0x8059fc3 in main (argc=1, argv=0xbffffcb0) at http_main.c:4830 Let me know if there's more information I can provide..
