This bug has been fixed in CVS.
Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
Thank you for the report, and for helping us make PHP better.
Current CVS (and thus the next snapshot) now handle arbitrary length
columns; enjoy!

I've added an arbitrary limit of 64k per text column for now, so that
PHP doesn't kill your apache instance off (it was trying to allocate
2GB + 1 bytes per text column).
It is likely that PDO_ODBC will now truncate any text columns that are
longer than 64k; I'm working on a better long term fix.
The very next snapshot should give you a more decent experience until
then.

Thanks wez, I've got PDO-ODBC working now with snapshot
php5-200507122030.
If I use PDO this shows up in err_log:
FATAL: emalloc(): Unable to allocate -2147483648 bytes
FATAL: emalloc(): Unable to allocate -2147483648 bytes
FATAL: emalloc(): Unable to allocate -2147483648 bytes
If I use the ifx_ functions this shows up in err_log:
[Wed Jul 13 09:26:51 2005] [notice] child pid 15980 exit signal
Segmentation fault (11)
[Wed Jul 13 09:26:51 2005] [notice] child pid 15981 exit signal
Segmentation fault (11)
Same problems basically, only happens when querying Informix text
fields, char and int are fine.
