Hi Kostya,
Looks like our new clang diagnostic from r210293 has caught a potential
issue in compiler-rt which is now breaking the build due to -Werror:
/home/dtoolsbot/build/sanitizer-x86_64-linux/build/llvm/projects/compiler-rt/lib/tsan/rtl/tsan_rtl_mutex.cc:460:6:
error: stack frame size of 536 bytes in function
'__tsan::ReportDeadlock' [-Werror,-Wframe-larger-than]
void ReportDeadlock(ThreadState *thr, uptr pc, DDReport *r) {
^

[ 93%] Building CXX object
lib/tsan/CMakeFiles/clang_rt.tsan-x86_64.dir/rtl/tsan_suppressions.cc.o
1 error generated.
Can you confirm that the stack frame report is legitimate?
Assuming it is, you'll probably want to either fix the function or relax
the byte limit passed to clang in your build system.
Let me know if I can help.
Alp.
