Address Sanitizer

Address sanitizers can be used to find memory allocation errors.

Windows

• Install the ASAN and Clang/LLVM tools with Visual Studio
• Build with /fsanitize=address according to https://docs.microsoft.com/en-us/cpp/sanitizers/asan?view=msvc-170
• Build setdll from https://github.com/microsoft/Detours
• Run setdll.exe /d:clang_rt.asan_dbg_dynamic-x86_64.dll on openstudiolib.dll, Qt5WebEngineCored.dll, Qt5WebEngineWidgetsd.dll, Qt5Cored.dll. This loads the ASAN runtime before Qt libraries which allocate memory on load.
