Hi Gabor,

Have you ran once, just to see if it passes all tests on your system?
There may be some system issues (with system libraries and tools).

Also, it's not just a matter of enabling the RT checkout, you need to
move it to the _get_sanitizer_builders(), so that it builds on
Compiler-RT changes as well as LLVM and Clang.

Finally, if you also want to restrict the back-ends that you build
(like I do) to make it faster, you still need to build the x86
back-end due to a problem in Compiler-RT's ASAN makefiles.

cheers,
