Must have been a gcc issue. Restarted machine and unpacked a fresh
tar.gz and it works fine. Soory to waste any time.

Please generate a backtrace with a DEBUG version of PHP
without heavy optimization flags.

BTW: I have an strace (from the version that crashes -- that is,
without the debug option)

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

"/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:
