$gdb sapi/cli/php core

$bt full

and add the output here?

nippur:/opt/install/source/php-4.3.0/sapi/cli # ./php core
Segmentation Fault (core dumped)

What is the second command?

please run :
gdb sapi/cli/php core

then under gdb type:

bt full

Don't forget the gdb at the beginning please.

Thank you.
