Re: [Libreoffice-commits] core.git: The -fvisibility-ms-compat hack is no longer needed for UBSan on Linux...

This is a heads up for anybody using Clang ASan/UBSan on Linux:

(1)  If you are using Clang trunk (towards Clang 9), make sure you have 
<https://github.com/llvm/llvm-project/commit/5745eccef54ddd3caca278d1d292a88b2281528b> 
"Adapt -fsanitize=function to SANITIZER_NON_UNIQUE_TYPEINFO".  Configure 
now assumes that "Clang >= 9" implies that fix, and otherwise building 
or running LO could fail.

(2)  I want to eventually get rid of the legacy 
NEED_CLANG_LINUX_UBSAN_RTTI_VISIBILITY code, so if you are using an 
older Clang, it would be great if you could upgrade as soon as 
convenient for you (and once Clang 9 is even out).
