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.

Thank you for not reading the 'how-to-report' and wasting my time.

Remove the non-PHP extensions first. There is no such thing as '--with-odbtp' in PHP. If the segfault still occurs, provide a gdb backtrace of it. Also provide the versions of the related build tools, such as GCC.

gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)

Do not file bugs when you have Zend extensions (zend_extension=)
loaded. Examples are Zend Optimizer, Zend Debugger, Turck MM Cache,
APC, Xdebug and ionCube loader.  These extensions often modify engine
behavior which is not related to PHP itself.
