Given your backtrace the segfault appears to be inside the PostgreSQL library and not PHP. If there are no more backtrace steps beside the 2 you've shown this is not a PHP bug.

I've submitted this bug to pgsql-bugs.

[2003-05-13 12:31 UTC] arousch at yahoo dot com

I get this core dump error too.  I am not using _any_ sql.  I'm just installing the mod_php4 for apache13.

and get:

Installing PEAR environment:      /usr/local/lib/php/

Looks like a case where openssl used for PHP is different version than the one used in pgsql.
