Re: [ros-dev] Error handling

[Phillip Susi]

I'm not sure what relation between goto and security vulnerabilities you 
are thinking of.  As for the labels you are going to, yes, when you 
write the code you will have to make sure you are jumping to the right 
place to do the proper cleanup that is required at that point in the 
code.  Figuring out which label you need to jump to though, is MUCH 
easier than figuring out all of the ( possibly dozens ) of lines of 
cleanup code you need to duplicate when you add a new operation and 
error check/recovery.
