From c46458e82f0112ed288bcf89bea973b859e1854e Mon Sep 17 00:00:00 2001 From: Max Kirillov Date: Mon, 19 Dec 2016 23:32:00 +0200 Subject: [PATCH] mingw: consider that UNICODE_STRING::Length counts bytes UNICODE_STRING::Length field means size of buffer in bytes[1], despite of buffer itself being array of wchar_t. Because of that terminating zero is placed twice as far. Fix it.
