Lines 14 and 16 are coverable, they should be shown as uncovered.
GCC suffers from a similar bug:
<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86411">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86411</a>.
Lines 10 and 12 should probably not be considered as covered, as we are
flushing the counters at line 8 and _exit is quitting the program without
writing out the counters. So anything that happens after line 8 should not be
counted.</pre>
