Python/C - Memory-Management

[Jonathan Epstein]

I have a similar problem with SWIG, which I haven't gone back to in a while.

When I do get back to it, though, I plan to either purchase a license for
Rational Purify, or just see how much I can accomplish using a free trial
license.

I believe that Purify runs on Windoze, Solaris and Irix.  If one or more of
these platforms are available to you, I suggest giving it a try.

It's pretty expensive, but about half the price on Windoze ($750?) as I
recall.

Oh, and please let me know how effective this is if you try it ;-)
