Does this happen with PHP 4.1.0RC5: http://download.php.net/~zeev/php-4.1.0RC5.tar.gz Previous Comments: ------------------------------------------------------------------------ [2001-12-06 14:46:30] [EMAIL PROTECTED] I have an old server running RedHat 6.2, Aolserver 3.0, PHP 4.0.6 (compiled as a module) and SquirrelMail (a webmail application written in PHP) 1.0.6 just fine. I'm trying to setup a new server with RedHat 7.2, Aolserver 3.4.2, PHP 4.0.6, and SquirrelMail 1.2.0-rc3 but I run into a consistent segfault. I haven't been able to write a script that abstracts the problem but it always happens at the same point in SquirrelMail: after you login, in the function squimap_mailbox_list (in functions/imap_mailbox.php). The offending line is functions/imap_mailbox.php:217: require_once('../src/load_prefs.php'); This file exists and is fine, and is require_once'd several times before this invocation (and I've stepped through other invocations of virtual_file_ex to see that it works) but this line always segfaults: backtrace: #0 0x400aedd3 in canonicalize ( name=0x82f9c38 "/usr/local/aolserver-3.4.2/servers/webmail/pages/squirrelmail-1.2.0-rc3/src/../src/load_prefs.php", resolved=0x40522edc "") at canonicalize.c:88 #1 0x402bde61 in virtual_file_ex (state=0x40523f0c, path=0x82c00dc "../src/load_prefs.php", verify_path=0) at tsrm_virtual_cwd.c:299 #2 0x402be427 in virtual_fopen (path=0x82c00dc "../src/load_prefs.php", mode=0x402d1e07 "rb") at tsrm_virtual_cwd.c:497 #3 0x40240a84 in php_fopen_and_set_opened_path ( path=0x82c00dc "../src/load_prefs.php", mode=0x402d1e07 "rb", opened_path=0x40528880) at fopen_wrappers.c:235 #4 0x402410b9 in php_fopen_with_path ( filename=0x82c00dc "../src/load_prefs.php", mode=0x402d1e07 "rb", path=0x402d35fb ".:/usr/local/lib/php", opened_path=0x40528880) at fopen_wrappers.c:391 #5 0x402412e8 in php_fopen_url_wrapper ( path=0x82c00dc "../src/load_prefs.php", mode=0x402d1e07 "rb", options=1, issock=0x40525050, socketd=0x40525054, opened_path=0x40528880) at fopen_wrappers.c:470 #6 0x4023ece1 in php_fopen_wrapper_for_zend ( filename=0x82c00dc "../src/load_prefs.php", opened_path=0x40528880) at main.c:477 #7 0x40222f06 in execute (op_array=0x84668d0, executor_globals=0x82282f8) at ./zend_execute.c:1999 #8 0x40220e03 in execute (op_array=0x821b2d0, executor_globals=0x82282f8) at ./zend_execute.c:1544 #9 0x40220e03 in execute (op_array=0x83cf358, executor_globals=0x82282f8) at ./zend_execute.c:1544 #10 0x40220e03 in execute (op_array=0x834c908, executor_globals=0x82282f8) at ./zend_execute.c:1544 #11 0x40220e03 in execute (op_array=0x83df304, executor_globals=0x82282f8) at ./zend_execute.c:1544 #12 0x4022f1cd in zend_execute_scripts (type=8, compiler_globals=0x839f938, executor_globals=0x82282f8, file_count=3) at zend.c:752 #13 0x402401c7 in php_execute_script (primary_file=0x405316cc, compiler_globals=0x839f938, executor_globals=0x82282f8, core_globals=0x839b6f0) at main.c:1206 #14 0x4023df92 in php_ns_module_main (ns_context=0x81ed510, sapi_globals=0x8276c50) at aolserver.c:434 #15 0x4023e1df in php_ns_request_handler (context=0x8184658, conn=0x819a8d0) at aolserver.c:519 #16 0x08077bb7 in Ns_ConnRunRequest (conn=0x819a8d0) at op.c:196 #17 0x0807e2c2 in ConnRun (connPtr=0x819a8d0) at serv.c:882 #18 0x0807dc10 in NsConnThread (arg=0x81f5178) at serv.c:671 #19 0x0811833b in NsThreadMain (arg=0x81f6590) at thread.c:228 #20 0x4002dc6f in pthread_start_thread (arg=0x40531be0) at manager.c:284 #21 0x4002dd5f in pthread_start_thread_event (arg=0x40531be0) at manager.c:308 and some extra gdb output: [right before the segfault] Breakpoint 9, canonicalize ( name=0x82f9c38 "/usr/local/aolserver-3.4.2/servers/webmail/pages/squirrelmail-1.2.0-rc3/src/../src/load_prefs.php", resolved=0x40522edc "") at canonicalize.c:88 88 rpath[0] = '/'; (gdb) print rpath[0] $94 = 0 '\000' (gdb) step Program received signal SIGSEGV, Segmentation fault. 0x400aedd3 in canonicalize ( name=0x82f9c38 "/usr/local/aolserver-3.4.2/servers/webmail/pages/squirrelmail-1.2.0-rc3/src/../src/load_prefs.php", resolved=0x40522edc "") at canonicalize.c:88 88 rpath[0] = '/'; (gdb) info local name = 0x82f9c38 "/usr/local/aolserver-3.4.2/servers/webmail/pages/squirrelmail-1.2.0-rc3/src/../src/load_prefs.php" rpath = 0x40521dec "" dest = 0x0 extra_buf = 0x0 start = 0x0 end = 0x0 rpath_limit = 0x40522deb "@" num_links = 0 rpath = 0x40521dec "" dest = 0x0 extra_buf = 0x0 end = 0x0 rpath_limit = 0x40522deb "@" num_links = 0 php config: ./configure --with-aolserver=/usr/local/aolserver --without-mysql --with-openssl --with-gettext I've tried this on whatever other platforms I have handy.
