[sc-users] Memory leak in Pattern:render

[Tim Walters <walters@xxxxxxxxxxxxxxxxxx>]

I tried rendering patterns for the first time last night. It's really 
cool, but seems to have a nasty memory leak. The following code leaks 
about 30 meg on my system:

---------

// make a big score
a = { Pbind(
	\dur, Pseq(({ rrand(0.125, 8.0) } ! 1024).normalizeSum * 30, 1),
	\freq, Pseq({ rrand(50.0, 4000.0) } ! 1024, 1),
	\amp, Pseq({ rrand(-48.dbamp, -12.dbamp) } ! 1024, 1),
	\attack, Pseq({ exprand(0.001, 0.2) } ! 1024, 1),
	\release, Pseq({ exprand(0.001, 0.2) } ! 1024, 1),
	\legato, Pseq({ [exprand(0.1, 1.0), exprand(1.0, 2.0)].choose } ! 1024, 1)
)} ! 8;

// render it
Ppar(a).render("foo.aif", 30);

---------

Since the whole reason I'm rendering is to quickly evolve, compare, and 
mutate large patterns in a long batch job overnight, this makes it 
somewhat useless for me. Am I doing something wrong, or is this a bug?

It seems to be dependent on the size of the score rather than the size 
of the rendered file.
