Reproducible also under Apache 2.0.44 with mpm-prefork; same
conditions, same trace.

FWIW, I can reproduce this every time on MPM-prefork Apache 2.0.43 and
PHP 4.3.0. No threads involved. This occurs after an 'apache2ctl
graceful' with gdb attached to the parent process (gdb stops on the
SIGUSR1, is continued, segv ensues). The server was started with
StartServers=1 and MinSpareServers=1, then the restart immediately
attempted, though it happens regardless of these.
This is linux 2.4.19 (Debian Woody/Sid hybrid), glibc 2.3.
Program received signal SIGSEGV, Segmentation fault.

I am also experiencing this bug. It is annoying because it causes
apache to silently die every night when the logrotate script runs
(installed from the "apache2-common 2.0.43-1" debian package)
install details:
Apache/2.0.43 (Debian GNU/Linux)
PHP/4.3.0RC4
php configure: ./configure --with-mysql=/usr --with-imap
--with-imap-ssl --with-apxs2=/usr/bin/apxs2 --with-gettext --with-xml
running mpm-prefork
error log:
[Fri Jan 10 11:59:41 2003] [notice] seg fault or similar nasty error
detected in the parent proces
"apache2ctl restart" doesn't crash when php module isn't loaded
If I can help, let me know!

Still occurs in 4.3.0
------------------------------------------------------------------------
[2002-12-10 16:00:46] thom at planetarytramp dot net
4.3.0 RC2 configured with:
'./configure' '--enable-experimental-zts'
'--with-apxs2=/usr/local/apache2-php/bin/apxs' '--enable-debug'
the phpinfo() function generates the page that is dumped to:
http://samizdat.positive-internet.com/~thom/phpinfo.html
the sequence is:
in ServerRoot:
bin/apachectl start
make connection to verify the server is running, resulting in the above
page.
bin/apachectl restart
apache dies at this point.
this is the error log:
