Operating system: Solaris 2.6
PHP version: 4.0.4pl1
PHP Bug Type: Apache related
Bug description: DSO loading and core dumped
I've tried to load the PHP 4.0.4pl1 shared object module(named "libphp4.so"). and I've
captured the truss message.
If I don't load the php DSO module, apache works very well.
But whenever I tried to load the php DSO module, apache core dumped.
When I examine the truss message, I think there is no problem to load the php DSO
module. But, other function causes the core dump.
I compiled the php DSO module as follows
./configure --with-apxs=/usr/local/apache/bin/apxs \
--enable-debug
Is this a php's bug or my mistake?
