When I'm working on certain nested abstractions in my patch (3 or 4 levels nested), and then I try and save, I get this error message multiple times (it looks like about 50 or 100 times in the main Pd window).

error: .x747af0: no such object

I also get error messages in the terminal I'm running Pd from that look like this:

bad window path name ".x713550.c"
bad window path name ".x713550"
bad window path name ".x713550"
bad window path name ".x713550.c"
bad window path name ".x713550"
invalid command name ".x713550.c"
invalid command name ".x713550.c"
invalid command name ".x713550.c"
invalid command name ".x713550.c"
invalid command name ".x713550.c"

The program then stops responding, and the main patch window suddenly closes. Patch windows don't respond to clicking the close box. Menus pop up if I click on them, but selecting menu items has no effect, with one exception: If I do File -> Quit from the main Pd window, it asks if I want to discard changes to the window. I say no, and then the abstraction nested n-1 levels (where n is the depth of the abstraction I was working on) pops up and I have a chance to save it. I save it, and then this whole thing repeats until I get to the root window (the main window of my patch). Once I save that, I click Pd's close box and it exits with a segfault. Anywhere in this process, if I click the main Pd close box, it exits with a segfault (although sometimes there is no segfault - I haven't figured the pattern out yet).

This whole thing happens for certain combinations of abstractions, but not others. I have this problem both on Mac OS and Linux.

I don't lose any work because of this - the saves seem to work fine - but I'm wasting a lot of time restarting Pd every few minutes. Help!

can you post an example of a patch that does this?

i have had similar errors before, i think they used to pop up when using the [playlist] external from the unuathorized library. but it never caused any harm.

my guess is that the errors are coming from some external that you are using, do you use the cyclone library or something? a lot of stuff in there i found really buggy.

I'm not using any externals at all. I'm attaching the patch and a couple of the files that it has trouble with. Open jake1.pd, then open one of the unit~ abstractions, and then open one of the delayj~ abstractions. Change something in delayj~, save it, and then the problems start.

I also get this message and a crash sometimes instead of a chance to save everything:
recv: connection reset by peer

Thanks a lot.

Can't unzip your example Myoozik, what did you pack it with?

i did what you said, and no errors here.

.. but the [midictl] , [miditog] bits don't open. are they externals or anstractions that you made yourself? if they are externals i'll guess that is where your errors come from.

if not, then post a message on the pd mailing list. someone there will know what invalid command name ".x713550.c" means at the code level.

(andy, attached a fresh zip here, hope it opens for you)

Thanks Hardoff. I looked at the patch Jake. Unfortunately I can't run it because you use
some externals or abstractions I don't have. Everything looking very nice though.

I've experienced similar problems with certain versions of Pd. I'm not sure of the exact conditions that cause it either so it's hard to file a bug, but the method I stick to when working is always save an abstraction the moment you finish editing it, before you
edit anything else, of course ymmv.
