<pre>To reproduce:
$ cat cov.c
#include <stdio.h>
int main() {
#include "cov.h"
}
$ cat cov.h
int i;
for (i = 0; i < 10; i++)
printf("hello\n");
$ clang -fprofile-instr-generate -fcoverage-mapping -o cov cov.c
$ ./cov
hello
hello
hello
hello
hello
hello
hello
hello
hello
hello
$ llvm-profdata merge default.profraw -o merged.profdata
$ llvm-cov show -instr-profile merged.profdata cov -format html -output-dir out
Now out/.../cov.h.html shows line coverage counts of 1, 11 and 10. But
out/index.html says the line coverage for cov.h is "- (0/0)"!
I'm using llvm and clang built from svn r295326.</pre>
