Then look at my last mail. Simple

dlopen(".../php_auth_vsbtuo.so", RTLD_NOW);
dlopen(".../libldap.so", RTLD_NOW);

fails. There are no php/apache modules involved, as apache is not in
question at all, and libphp4.so is not found.
It just simple does not happen with simple 'int a;' shared libraries.
Or I at least did not found how to trigger it. OK, I understand you,
I'll look at figure 1.
