applications compiled with tsan (-fsanitize=thread) option fail to start with 3.19.0-41-generic kernel

[Dmitry]

Consider the following code:
# cat test.c
int main()
{
        return 0;
}

Now compile it with clang-3.5 and -fsanitize=thread option and run:
# clang-3.5 -fsanitize=thread -fPIE -pie test.c
# ./a.out
FATAL: ThreadSanitizer can not mmap the shadow memory (something is mapped at 0x5650b0bb2000 < 0x7cf000000000)
FATAL: Make sure to compile with -fPIE and to link with -pie.
# cat /proc/sys/kernel/randomize_va_space

This regression appears in 3.19.0-41-generic kernel. The example above runs fine (without FATAL errors) with previous 3.19.0-39-generic kernel.

The problem is still present in 3.19.0-42-generic kernel.
After bisecting code, I've found that problem was introduced by 06ec92f3bac598a7a9b9ecf451ab1915929a5980 commit - http://kernel.ubuntu.com/git/ubuntu/ubuntu-vivid.git/commit/?id=06ec92f3bac598a7a9b9ecf451ab1915929a5980

Looks like I should update compiler and not use -pie option any more.
