Crash in latest Max 6.0.5 but works fine in Max 5

May 29, 2012 | 11:04 pm

While it appears that the scheduling issues I encountered in earlier versions of Max 6 are solved in 6.0.5, I’ve run into a new problem. It’s clearly timing related because I can’t control exactly WHEN it will happen but I can pretty confidently make it happen in reasonably short order by sending a lot of OSC data from my Eigenharp Alpha into Max 6 (I don’t believe the problem is with the OSC stuff though).

While Max 5 behaves perfectly fine, Max 6 will crash within 5 to 15 seconds of my just sliding my hand over multiple keys of the eigenharp.

I’m wondering if someone can tell from the stack trace what might be going on. For example, what object might jbox_updatetextfield_safe be referring to?

Thanks,
David

Well, that’s a good question (and the support team queried this as well). The problem is that my ‘patch’ contains many sub patchers and abstractions and this use of a message box is not something I tend to use other than accidentally. So it’s going to be a headache to find it.
Anyone know of good tools for finding particularly configured objects in a nested folder?

If I knew which .maxpat file to open, this would not be an issue. The problem is that my system is made up of (at this point) hundreds of abstractions and other patchers so it’s almost literally looking for a needle in a haystack.

I could do a recursive grep but the problem there is that I would get every single ‘message’ object in my environment.

So I really need a better mechanism for searching that recognizes connections as well.

Speaking of better mechanisms, what I would kill for is a visual "diff" so that I can compare different versions of max objects that are checked into my version control system.

All the ‘diff’ systems for comparing different versions of a file are text based. But it’s almost impossible to use them with max patchers because, when you make even a minor change, the objects get reordered in the file and so the textual changes look huge to a diff tool.

So it would be extremely useful to have a tool that can visually display two versions of a patcher, highlighting the areas that are different. Non-trivial but probably a very interesting project (any grad students out there looking for a project?)

Yeah, I shouldn’t have mentioned ‘diff’ — that’s a red herring in terms of my problem. I don’t know how Shark would help me — we already believe it’s a messagebox (an object supplied by Cycling74) that’s causing the issue — the question is finding WHICH message box in a large number of patchers and abstractions is responsible.
