Emacs on Win32 crashed with BSOD when built with image support.

[Zhichao Hong]

Symptoms:

I have built emacs on Win32 from CVS HEAD using MingW with GnuWin32
image support.
In some cases, it crashes with bsod (blue screen of death) when I tried to click
the minimize button on the frame title bar.

This problem does not happen with a MSVC build without image support.
