ID: 17414 Comment by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: Apache2 related Operating System: Linux PHP Version: 4.3.0 Assigned To: aaron New Comment:
Reproducible also under Apache 2.0.44 with mpm-prefork; same conditions, same trace. Previous Comments: ------------------------------------------------------------------------ [2003-01-20 04:39:55] [EMAIL PROTECTED] FWIW, I can reproduce this every time on MPM-prefork Apache 2.0.43 and PHP 4.3.0. No threads involved. This occurs after an 'apache2ctl graceful' with gdb attached to the parent process (gdb stops on the SIGUSR1, is continued, segv ensues). The server was started with StartServers=1 and MinSpareServers=1, then the restart immediately attempted, though it happens regardless of these. This is linux 2.4.19 (Debian Woody/Sid hybrid), glibc 2.3. Program received signal SIGSEGV, Segmentation fault. 0x40585181 in sapi_initialize_empty_request (tsrm_ls=0x8108740) at /usr/src/apache/php/php-4.3.0/main/SAPI.c:399 399 SG(server_context) = NULL; (gdb) bt #0 0x40585181 in sapi_initialize_empty_request (tsrm_ls=0x8108740) at /usr/src/apache/php/php-4.3.0/main/SAPI.c:399 #1 0x4057f8ec in php_module_startup (sf=0x40605360, additional_modules=0x40605540, num_additional_modules=1) at /usr/src/apache/php/php-4.3.0/main/main.c:1035 #2 0x405c820e in php_apache2_startup (sapi_module=0x40605360) at /usr/src/apache/php/php-4.3.0/sapi/apache2filter/sapi_apache2.c:269 #3 0x405c89cd in php_apache_server_startup (pconf=0x80c3c30, plog=0x80fbd10, ptemp=0x8101d28, s=0x80c6298) at /usr/src/apache/php/php-4.3.0/sapi/apache2filter/sapi_apache2.c:556 #4 0x0807fe59 in ap_run_post_config () #5 0x08085e11 in main () #6 0x402409f1 in __libc_start_main () from /lib/libc.so.6 ------------------------------------------------------------------------ [2003-01-10 15:21:12] [EMAIL PROTECTED] I am also experiencing this bug.
