--- Comment #6 from Zequan Wu <zequanwu at google.com> ---
> The right way to solve is to emit a gap area between the end of each statement which may terminate its region, and the start of the next statement. However, there's a chance this could blow up the size of coverage mappings.
I think we could add a gap region between two statements only if the first
statement contains a terminating statement like return, continue, break etc.
