Source Code
When instantiating a macro within a macro and the first 2 cases are not
covered, the rest of the file is wrongly classified as uncovered.
The segment building in CoverageMapping.cpp seems to lead to a wrong order,
thus skipping valid segments later when displaying them. I guess it has to do
with the types of the coverage regions.
I have attached a minimal example and the script I use to test this behaviour.</pre>
