Summary: Massive memory leak in array module
Initial Comment:
Simplified variant of a test program from c.l.py:
.import array
.
.def test():
. for x in xrange(1000000):
. b = array.array('B', range(120, 120+64))
.
.test()
On Win98 under 2.3, it zooms to 200MB in a few
seconds. No growth under 2.2.3 (it stays under 2MB
until it finishes).
Problem goes away if
. b = range(120, 120+64)
instead. Problem also goes away if
. b = array.array('B', range(64))
instead. I expect (but ave not confirmed) that in the
latter cases it's leaking refcounts (to the immortal "little
integers").
