gdal_calc causing python.exe stopped working

[miro]

Whenever I use gdal_calc.bat through subprocess in python script or if I just open OSGeo4W Shell on Windows 7 64bit and write "gdal_calc" I got "python.exe stopped working" pop up window. In script the calculation works, it is just this window which pop up and if closed it continues no problem...

GDAL 1.11.0, released 2014/04/16
