Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

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.

Remove old stuff:
- pear uninstall pdo_odbc
- pear uninstall pdo
Grab a PHP 5.1 snapshot from http://snaps.php.net:
- Extract it
- cd into the dir
- ./configure <your usual options> --with-pdo-odbc=unixODBC
- make
- make install
then test it
