boris, can you strip down your configure line to ./configure
and also update your sources ? if the segfault is gone, add one one
each from you original ./configure line and try again.
trying to narrow down the problem :)

When I said w/o mailparse I meant a fresh compilation of php without
mailparse. Only:
--with-mysql=/usr/local/mysql \
--with-apxs=/usr/local/apache/bin/apxs \
--enable-ftp \
--enable-track-vars \
--enable-trans-sid \
--with-gd \
--with-pdflib \
--with-jpeg-dir=/usr/lib \
--with-tiff-dir=/usr/lib \
--with-png-dir=/usr/lib \
--with-zlib-dir=/usr/lib \
--with-gettext \
--with-imap \
--enable-sockets

err, somehow I didn't see the backtrace...

Are you using the absolute latest version of mailparse from CVS?
I fixed some segfault related issues the other day.
Also, we *really* need a backtrace to sort this out.
When you say without mailparse, is mailparse not used in the script, or
not actually compiled in?

Playing around with some versions:
Current CVS CLI with mailparse => Segfault
Current CVS CLI w/o mailparse => Segfault
PHP 4.2.3 w/o mailparse => OK
PHP 4.2.3 with mailparse => Segfault
