Description
Currently, the build fails with OpenSUSE Tumbleweed and gcc (SUSE Linux) 12.2.1 20220830:

Looks like an upstream issue. The following code is a simplification of the real PhysX code, but it compiles fine on older versions of GCC.
#include <iostream> #define PX_NOCOPY(Class) \ protected: \ Class(const Class&); \ Class& operator=(const Class&); template<class T> class BufferedPreallocatingPool { private: T m_var; PX_NOCOPY(BufferedPreallocatingPool<T>) public: BufferedPreallocatingPool() : m_var{} { std::cout << "Allocated " << m_var << std::endl; } }; int main() { BufferedPreallocatingPool<int> x; }
