Hi. Thank you for the report. It's caused by fact that LLVM switch in 4d474e078ac7 to c++14. So that I suggest to use gnu++14.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests. I also verified that abidiff is equal for all libsanitizer shared libraries. I'm going to install the patch if there are no objections. Thanks, Martin
