Description:
------------
OS: FreeBSD 6.2 am64
trying to compile latest PHP 4.4.4 (also tried fresh snapshot php4-STABLE-200701271330) with curl 7.16.0

./configure \
--with-gd=/usr/local \
--with-apxs2=/usr/local/apache2/bin/apxs \
--with-mysql=/usr/local/mysql \
--with-mysql-sock=/tmp/mysql.sock \
--with-freetype-dir=/usr/local \
--enable-gd-native-ttf \
--with-jpeg=/usr/local \
--with-jpeg-dir=/usr/local/include \
--with-png-dir=/usr/local/include \
--with-zlib-dir=/usr/local/lib \
--enable-ftp \
--enable-sockets \
--with-curl=/usr/local

after make install got the error:

Apache does segfault on start with libphp4.so activated.
These all problems appear when using --with-curl

Remove --with-mysql from the configure line to make sure your problems are not caused by conflict between YaSSL used in MySQL and OpenSSL.

you right. it compiles well with either curl or mysql.
i removed --with-mysql and "make install" worked without segfault.

But i need both curl and mysql. what should i do?

Upgrade mysql client to the latest available version, AFAIK it's fixed there.
Not PHP problem anyway.
