 I can see how "FormatMessageA" is looked up. That's wrong.
 It should be "FormatMessageW", because I'm running XP.
 
 Marshal.SystemDefaultCharSize is 2, which is correct.

+Sorry, I've misunterstood the dump output. It was LoadLibraryA,
+not FormatMessageA. FormatMessageW is looked up correctly :-)
+
+
+The problem is the following icall:
+
+	{"PtrToStringAuto(intptr)",
+ves_icall_System_Runtime_InteropServices_Marshal_PtrToStringAnsi},
+	{"PtrToStringAuto(intptr,int)",
+ves_icall_System_Runtime_InteropServices_Marshal_PtrToStringAnsi_len},
+
+As you see, "Auto" gets mapped to "Ansi".
+
+Under Windows this is wrong. It should be mapped
+to a function which depending on Marshal.SystemDefaultCharSize
+it calls either *Ansi or *Unicode.
