warning: statement will never be executed [-Wswitch-unreachable] #31

Closed aka-LJ closed 4 years ago

Hello,

I have built and run the package without any error, but getting the warning message of the state will never be executed at the building stage.

My point cloud data contains invalid data and I used pcl::removeNaNFromPointCloud() to filter the invalid data.

However, I still don't get any msg published to the topic, not sure the package is not working because of the invalid data or the building process.

here is the warning :

just the count won't be executed, won't affect the switch case
