Crash on exit in qt5winextras.dll Windows XP 32

GUI widgets(c++) application is built with the latest Qt Creator, Qt 5.4.1 MinGW SDK(qt-opensource-windows-x86-mingw491_opengl-5.4.1.exe) on Windows 8.1 x64 PRO file:

QT       += core gui network winextras

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

Everything is by defaults, not special settings. App runs and works on Windows XP x86 SP3 but when closed it crashes giving a generic windows "Send error to Windows" dialog.

Windows Logs show that the crash occured at qt5winextras.dll version 5.4.1.0 adress 0x00008009

Doesn't crash on Windows 7 and 8.1

Can this be Qt bug? How to fix this?
