I've read them now and they are very impressive. But I didn't found
anything about api changes or something else that would explain the
error message I get when I try to connect with php.

I've also pried into the firebird2 code and found that the error is
caused by parameter checkings in ClumpletReader::getClumpletSize(). So
the reason may be the way php is calling isc_attach_database(). But
really tracking this down is far beyond my c and c++ possibilities ...
