Bug #3315: PHP w/ MySQL crashes apache - Same bug as in #2187 & #3168

From: john@mehringer.com Operating system: RedHat 6.1 PHP version: 3.0.14 PHP Bug Type: MySQL related Bug description: PHP w/ MySQL crashes apache - Same bug as in #2187 & #3168 Using RPMS: apache-devel-1.3.9-8 apache-1.3.9-8 MySQL-client-3.22.29-1 MySQL-devel-3.22.29-1 MySQL-shared-3.22.29-1 MySQL-3.22.29-1 Compiled PHP-3.0.14 using: ./configure --with-apxs=/usr/sbin/apxs --with-mysql make make install Starting apache with the php module causes a segfault. It has something to do with the MySQL switch because if I don't configure --with-mysql the module loads fine. I ran apache in single process mode and saved the core dump. /usr/sbin/httpd -X using GDB and looking at the stack trace I get. (gdb) where #0 0x40371954 in ?? () from /usr/lib/libz.so.1 #1 0x40165fa8 in __getservbyname_r (name=0x4030ba76 "mysql", proto=0x4030bd10 "tcp", resbuf=0x4019115c, buffer=0x80aba00 "mysql", buflen=1024, result=0xbfffd9fc) at ../nss/getXXbyYY_r.c:182 #2 0x40165e24 in getservbyname (name=0x4030ba76 "mysql", proto=0x4030bd10 "tcp") at ../nss/getXXbyYY.c:123 #3 0x402dba8a in php3_minit_mysql (type=1, module_number=9) at functions/mysql.c:258 #4 0x402c0367 in module_startup_modules () at internal_functions.c:533 #5 0x402b9b0a in php3_module_startup () at main.c:1237 #6 0x402b779e in php3_create_dir () from /etc/httpd/modules/libphp3.so #7 0x8053fd4 in ap_single_module_configure () #8 0x804f14d in ap_get_server_built () #9 0x8052f44 in ap_clear_module_list () #10 0x805350c in ap_handle_command () #11 0x8053558 in ap_srm_command_loop () #12 0x80538c7 in ap_process_resource_config () #13 0x8053f44 in ap_read_config () #14 0x805ae47 in ap_child_terminate () #15 0x805b4fb in main () #16 0x400b81eb in __libc_start_main (main=0x805b290 <main>, argc=2, argv=0xbffffce4, init=0x804e684 <_init>, fini=0x80794ec <_fini>, rtld_fini=0x4000a610 <_dl_fini>, stack_end=0xbffffcdc) at ../sysdeps/generic/libc-start.c:90 So it looks like the problem comes from "functions/mysql.c" line 258 if ((serv_ptr = getservbyname("mysql", "tcp"))) Let me know if there is anything I can do to help further. - John
