Answer 1

The issue logged in the valgrind official issue management system. Julian Seward has fixed it in 3.9 later version. https://bugs.kde.org/show_bug.cgi?id=336435

This is cause the internal problems of thread managing in valgrind. I had same problem and it was fixed in 3.10 version of valgrind.
