Hi Maxim, Thanks a lot for the information. I find it very useful for my future tests.
Also I found this page maintained by ASAN developers https://github.com/google/sanitizers/wiki/AddressSanitizerClangVsGCC which lists some of the differences. Finally any plans to integrate other sanitizer tools by LLVM in to GCC, like Memory Sanitizer, Data Flow Sanitizer ?
