// NVCC sometimes cannot process plain assert() from <cassert>, so
// we need to provide our own implementation that works around the bug
// by avoiding the __PRETTY_FUNCTION__ macro where it causes problems.
// A bug for this has been filed by Philippe Canal at the link below:
// https://developer.nvidia.com/nvbugs/cuda/edit/1729798
