hmm, the problem is when the real_value_hnd is called, the signal_startup has
not

Just tried with 5.3.9RC4, and the problem does not occur. Seems to be something
in 5.4

I have the same problem on Solaris 11 (express) i86pc. I'm not sure about ZTS
mode (I have NOT set --enable-maintainer-zts)
I have compiled php-5.4 (various versions, the latest one being 5.4.0RC4) with
the following configure flags:
--with-apxs2=/usr/local/apache2/bin/apxs --with-openssl=/usr/local/ssl
--with-openssl-dir=/usr/local/ssl --with-zlib --enable-sockets
--enable-shared=yes --enable-static=yes --prefix=/usr/local/apache2/php
--enable-calendar --disable-ftp --with-mysql=/usr/local/mysql
--with-imap=/usr/local/imap --with-imap-ssl=/usr/local/ssl --enable-flatfile
--without-recode --disable-ipv6 --with-mysql-sock=/var/run/mysql/mysql.sock
--with-gettext=/opt/csw --enable-libxml --with-db4=/usr/local/BerkeleyDB
Builds and installs fine.
But during apache (2.2.21) startup, it segfaults and dumps core:
# /usr/local/svc/init.d/apache2 restart
Restarting Apache2 httpd ...
/usr/local/apache2/bin/apachectl: line 80: 17568: Memory fault(coredump)
In fact, uncommenting all php_admin_value lines from apache config file, apache
starts normally.
When compiling and installing 5.3.6 with the same configure options, the
problem does not occur.

segfault occurs during apache config analyse.
If config doesnt have any php_flag, php_value,... apache starts and works as
expected.
