--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
Well, I guess it's caused by exception handling edges:
1: 12: std::cout << val << std::endl;
call 0 returned 100%
branch 1 taken 100% (fallthrough)
branch 2 taken 0% (throw)
call 3 returned 100%
branch 4 taken 100% (fallthrough)
branch 5 taken 0% (throw)
With -fno-exceptions these edges will disappear:
1: 12: std::cout << val << std::endl;
call 0 returned 100%
call 1 returned 100%
-: 13: }
Thus, I'm closing that as invalid.
