Description

Calling cv.CreateHist() with a mutable object results in the object being modified and memory being corrupted. See example code below:

In r1: import cv
In r2: dims = r180
In r3: ranges = [(0,180)]
In r4: a = cv.CreateHist (dims, cv.CV_HIST_ARRAY , ranges, 1)
In r5: dims
Outr5: []
In r6: ranges
Outr6: [(0, 180)]
*** glibc detected *** /usr/bin/python2.6: double free or corruption
(fasttop):
0x08f24b78 ***

Tested with svn -r2425. CmakeCache.txt from build attached. Os is Gentoo/Linux 32 bits.
