Hi all,

i found a strange "bug" while compiling the attached c++ file

> g++ -c x.cpp
x.cpp: In member function 'std::pair<int, int> X::getImp() const':
x.cpp:15:57: error: invalid static_cast from type 'XBase' to type 'int'

if I remove any of the superfluous statements in x.cpp it works fine!

mario.
