It's quite possible that PDO is doing something that unixODBC or informix doesn't like, but the problem is that unixODBC is trying to call a function that is set to NULL.

What I suspect is the problem is that either informix doesn't set a flag to tell unixodbc about the functions it supports, or that unixodbc doesn't respect a flag that it should. Ultimately, unixODBC should catch that NULL and report an error properly. I don't think I can do anything while this crash problem exists, and I think you should file a bug report with the unix ODBC guys so that we can figure out what is going wrong, and then we can figure out how to make things work for you. I'm happy to co-operate with them in tracking this down. ------------------------------------------------------------------------ [2005-09-10 21:47:04] [EMAIL PROTECTED] That crash looks like the informix libraries are trying to call a NULL callback handler. There's no way I can debug this without being able to sit down at the machine with my hands on gdb; Can I get a non-privileged account on that machine, so that I can build a CLI php and test it? ------------------------------------------------------------------------ [2005-08-03 08:41:40] [EMAIL PROTECTED] Wez, the fix didn't quite fix it? :) (note to myself: need to get my eyes checked) ------------------------------------------------------------------------ [2005-08-03 06:32:45] scott dot barnett at thuringowa dot qld dot gov dot au Still having build problems.
