Comment at: compiler-rt/lib/sanitizer_common/sanitizer_win.cpp:731
+// On this environment, __asan_init is called during global constructor phase,
+// way after calling the .CRT$XID initializer.
+static int (*volatile queueOrCallAtExit)(void (*)(void)) = &queueAtexit;
----------------
So... is the root issue that C++ global constructors are executed after the `.CRT$XID` initializer in MSVC environments, but before in mingw environments? I believe they're supposed to be compatible, so if there's such a discrepancy, maybe we should also consider trying to fix it in mingw-w64 crt?
