Summary: ASan needs to initialize before ucrtbase.dll so that it can intercept all of its heap allocations. New versions of dbghelp.dll depend on ucrtbase.dll, which means both of those DLLs will initialize before the dynamic ASan runtime. By lazily loading dbghelp.dll with LoadLibrary, we avoid the issue. Eventually, I would like to remove our dbghelp.dll dependency in favor of always using llvm-symbolizer.exe, but this seems like an acceptable interim solution.
