Minimal working example
This is on Ubuntu 17.04, gcc 6.3.0.
Running (note that glog has to be installed):
g++ -c hybrid_grid_points_processor.cc -Werror=return-type
gives:
hybrid_grid_points_processor.cc: In function ‘FlushResult Flush()’:
hybrid_grid_points_processor.cc:26:1: error: control reaches end of non-void
function [-Werror=return-type]
}
When -O1 or -O2 or -O3 is added, compilation is successful.
Minimal working example (hybrid_grid_points_processor.cc) has been attached.
