Well, that was the backtrace before I did a debug version. When I
changed the CFLAGS to add -g as you suggested and added --enable-debug
then it no longer crashes.

What this backtrace generated with debug build of PHP?
The backtrace should've been more detailed if it was.

The line in the Makefile gets expanded to this:
/root/webserver_software_tmp/php-4.3.5RC3/sapi/cli/php -n
-dshort_open_tag=0 -dsafe_mode=0

"/usr/local/lib/php" -b "/usr/local/bin"
/root/webserver_software_tmp/php-4.3.5RC3/pear/package-*.xml
gdb on the above has a bt of:

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.
set CFLAGS to -g, add --enable-debug to your configure and
if it still crashes generate a backtrace.
