There are a few places where we (improperly) directly call malloc()
instead of PyMem_Malloc(), so yes, you should rebuild numpy against
TCMalloc in addition to the Python interpreter.
How do I build against the -ltcmalloc library? Just not sure how to
input compile time arguments with the build

Memory usage stays constant with Ubuntu 11.04, 64-bit, using the numpy
1.5.1 package from ubuntu, and using 1.6.1.dev-a265004.

Further isolated the error and it seems to come in from the sum function in
numpy. I will probe further later but the code below causes the memory usage to
go up and up. If you change sum below to some other function there are no
issues.
from numpy import arange, sum
for x in range(1

Much reduced code exhibiting the issue. This shouldn't use much memory
but just keeps going up and up because the copied window I assume gets
left around and not taken up by the garbage collector.

Hi
I've been looking at various labelled-array packages, including Pandas
(https://github.com/wesm/pandas) and datarray
(https://github.com/fperez/datarray).
I was quite interested in the design discussion for datarray, and I had
a couple of questions:
1) Is this mailing list the correct plac

Sorry. I attached here the class and script to run it. It is just a
minimalistic example of what I'm really doing that exhibits the same
behavior. All the script does is run at.createSpecific after
instantiating the class. I have seen this exhibited on many other cases
but it runs fine in Windo

What do you mean by "5 x 5 of array slices containing the long
