I got again the latest CVS and compiled it with

./configure --prefix=/etc/httpd \
        --with-apxs=/usr/sbin/apxs \
        --with-config-file-path=/etc/php4/apache \
        --enable-debug=yes \
        --with-exec-dir=/usr/bin \
        --with-system-regex \
        --with-mysql=/usr/local/mysql \
        --with-pgsql=/usr/local/pgsql \
        --with-gd=/usr \
        --with-freetype-dir=/usr\
        --with-zlib \
        --with-ldap \
        --with-imap \
        --enable-track-vars \
        --enable-magic-quotes

and then there was NO segfault, but in the browser appeared (the
differences is of course --enable-debug=yes)

I hope it is clear, if there is something else I can do please tell
me!

P.S. the view in the browser (probably in the error_log) is somehow
different on different cases, but I suspect it's from the query and the
number of notices from the postgresql server. The lines that are
[error] NOTICE: are actually the messages from the postgre.

We can't do much without a backtrace. Can you try to get one? See
http://bugs.php.net/bugs-generating-backtrace.php for instructions.

------------------------------------------------------------------------

[2002-03-26 12:37:33] [EMAIL PROTECTED]

pg_last_notice() causes segmentation falts when the postgresql
generates notices. I mean when there are no messages from the DB server
(RAISE NOTICE ....), pg_last_notice does not generate errors, but when
the DB server generates notices they are sent to the apache log file
(which I find strange), and with them SegFault for the apache child.

I used php-4.1.2 the bug is presented, I get the CVS from 25 March and
the problem still exists.

P.S. if it is necessary I may try to generate backtrace, but the last
time I tried I didn't succeeded :(
