pfft~ in poly~ crashes?

November 5, 2011 | 5:43 pm

I have a very weird and bad crash in a big complicate patch, apparently due to poly’s out~.
The structure is like this: I have a poly~, having a subpatch containing itsself a poly~ inside. Inside this second poly I have all standard MSP treatments (no weird object), but here’s the "funny" part: one of those object inside this second poly~ is a [pfft~ gizmo_loadme]. As soon as I get rid of it, I have no more crashes.
As soon as I put it back, if I try to run two "run" two instances of the first poly, rainbow-wheel for some seconds, and crash.

I was wondering if there’s somebody who had the same issue, or a similar one, and I tried to reproduce the thing.
I built a very simple poly~ in poly~ situation (with a play~ in the inner poly~), and I had a bad crash at saving time. So I’m puzzled. Of course, I completed the full smaller example, and everything worked in the simple one.
Is there maybe some known incompatibility between gismo~ and other stuff?

I’m on Max 5.1.9, but I tried in Max 6 and I still have crashes.

Hi Daniel,
I a very big patch I also have a crash with a poly~loading a Gizmo~.
The problem for me seems to be related to the poly’s input.

There is something weird, I have a mono version of my patch who works very well and the stereo version crash when I start the audio chain.

Do someone know a way to fix this issue?
Philippe.

Hi Daniel,
Finally, after some modifications in the patch’s structure, without modifications in the poly~itself… The crashreport changed and is now really close to yours.

I have the same problem – pfft~ works outside a poly~, but crashes when I put it inside a poly~. For me this problem only comes with Max 6, not with Max 5.

I don’t have a solution, but found something else: if I first use a patch with the pfft~ *not* in a poly~, then I can then use it in a poly~ without the crash, until I restart Max, and then the problem returns.

This means that a temporary fix is to put one copy of the pfft~ on the top level of the patch – then all the others inside poly~s seem to work without crashing.

I’d be interested to know of any proper solution.

John

Thanks Phillippe, Thanks John,

it’s been a while I haven’t checked this thread.

Does anybody know if the problem has been focused and solved with 6.0.5?
I’m still in Max 5 and I could not solve the issue, which is quite frustrating…

Daniele

John, your method does not seem to work for me.
I’ve put an instance of the gizmo_loadme inside a pfft in the main level, and yet it crashes again:
