From: bleyton@cpe-usalco.com Operating system: AIX 4.2.1 PHP version: 4.0 Latest CVS (07/12/1999) PHP Bug Type: Reproduceable crash Bug description: Segfault with Openlink I'm getting consistent crashes when trying to connect to an odbc data source. This was occurring with Beta 3, and appears to still exist in current CVS code. I'm somewhat new with this backtracing stuff, so hopefully the following is useful. If not, please let me know what I need to do to get a useful backtrace: # gdb httpd GDB is free software and you are welcome to distribute copies of it under certain conditions; type "show copying" to see the conditions.
