Description:
------------
When both php-odbc & php-pgsql are installed an attempt to read data thru the pg_lo_read_all() function causes a segmentation fault. Removing the php-odbc module eliminated the problem. The following setup is being used

Linux 2.6.1
Apache 2.0.48
PHP 4.3.4
PostgreSQL 7.4.1

Reproduce code:
---------------
Load both the php-odbc & php-pgsql module and attempt to read large object data from a PostgreSQL database using pg_lo_read_all(). Run from the command line to see the segmentation fault error, or look in the apache error log

Can you point me in the right direction on how to generate the a backtrace, an example or a howto site. Thanks

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.

We have a nice "quick fix" for this, but Ilia didn't use it... so here it is :-)
