Description

The following code works fine

1small_img = cv2.resize(img, (ncols, nrows))

But if it is called in a function like:

1def my_resize(img):
2    small_img = cv2.resize(img, (ncols, nrows))
3my_resize(img)

It crashes python.exe

environment:
win 7 32 bit
opencv 2.3.1
mingw 4.4
cmake 2.8

Hi! I can not reproduce the bug. We actually have substantial number of problems with MinGW. I would recommend you to use MSVC instead (since you are using Python, it should not matter which compiler you use; you can build cv2.pyd with a free Visual Studio Express 2010, or take precompiled cv2.pyd from OpenCV 2.3.1)
