There doesn't seem to be anything wrong with your example code above, but
the problem might be in the other things that you have omitted. Does
anything else use the same resource lock name? If so, those are most likely
the cause. The code above on its own should not be able to lead to the
behavior you have described, since the use of RESOURCE_LOCK only has the
effect of preventing tests with the same named resource from running
concurrently. It doesn't touch any files directly, only your tests
themselves would be doing that. The other thing I would check is the
specific reason why the compare_results test is complaining with the
message "permission denied". Maybe add more debug logging to the test case
to check what you expect to exist (or not exist) at the start of the test.
You can also make ctest show more output by adding the -V option which will
show all the commands and test output.
