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:

Have contacted user to see if problem still occurs with latest release of PHP.
 [2000-07-24 17:38 UTC] zak@php.net 
This bug was not confirmed or resolved.
User attempted install of later releases, but could not get them to compile.

I will try to find if the bug exists in more current releases of PHP on AIX.

user feedback:

I gave up on it a long time ago.  Never was able to get any version to work.

anyone with access to AIX willing to test this?
 [2001-04-03 12:10 UTC] sniper@php.net 
No need to keep this in bug db.
