       [notice] child pid 13927 exit signal Segmentation fault (11)

-> this is what comes in the apache error log when I call the script
with a php higher than 4.0.2. with the 4.0.2 it works fine. The page output
is most of the time incomplete (stoping at a random place), but no "document contains no data", or very seldom.

1) the scripts source are visible under http://www.omnis.ch/dev/php/
    (my first php script ever, 2 years ago, could be improved I know: but
     it still should work without killing my webserver....)

2) config.nice :
#! /bin/sh
#
# Created by configure

"./configure" \
"--with-apxs=/usr/local/apache/bin/apxs" \
"--enable-track-vars" \
"--enable-safe-mode" \
"--with-gd=../gd1.3" \
"--with-ttf" \
"--with-mysql=/usr/local" \
"--with-ldap" \
"--with-xml" \
"--with-zlib" \
"--with-zlib-dir" \
"--enable-memory-limit" \
"--with-recode" \
"--with-dbase" \
"--with-pdflib=/usr/local/src/web/pdflib3" \
"--enable-ftp" \
"$@"

(also tried to remove some or all the modules -> no change)


3) no changes in php.ini (original file.dist)

4) linux server, intel, distribution: suse 6.4
