PHP 4.0 Bug #5851: IBM DB2 support crashes httpd, but not httpd -X

From: truth@ichaos.com Operating system: RedHat6.1, latest patches PHP version: 4.0 Latest CVS (29/07/2000) PHP Bug Type: Reproduceable crash Bug description: IBM DB2 support crashes httpd, but not httpd -X This problem cropped up when upgrading to PHP4 from a working installation of PHP3 (does PHP4 use IBM DB2 differently?) Configure line is ./configure --with-ibm-db2 (yes, thats it!) httpd -X starts up fine and works. Running httpd via the standard method gives this error in the log files: [Fri Jul 28 10:11:38 2000] [notice] child pid 17805 exit signal Segmentation fault (11), possible coredump in /etc/httpd running a backtrace with "gdb httpd /etc/httpd/core" gives the following: [root@Sleepy httpd]# gdb httpd /etc/httpd/core GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.
