Hello,

I have a problem with touchOSC causing pd to crash.

It's this combination that crashes pd every time:

1. use |routeOSC| to extract the values from touchOSC
2. switch between pages on the iPod
3. no error message, but crash

I've tested it several times with the modified basic.pd patch from http://hexler.net/docs/touchosc-getting-started-osc: no problem at first, but then a crash when |routeOSC| is added.

So, I assume it has something to do with the mrpeach library, since there are no issues with midi or with |dumpOSC| alone printing the messages (but I need |routeOSC| to use the messages). Also it's independent on edited or standard layouts of touchOSC.

Both, the patch an a crash-report are in the attachment. I'm using a 5th gen. iPod + MacBook, OSX 10.6.8.

I would be really thankful, if someone could help! There were posts about this problem here and in the www - but no real hint for a solution.

Thanks!

did you try
[mrpeach/udpreceive 8000]
|
[mrpeach/routeOSC /bla]

and

[mrpeach/packOSC]
|
[mrpeach/udpsend]

yes, i tried, but no success. it's the same with your patch: as soon as i switch between pages pd crashes.

although i don't really understand the crash log from console, i think the last 'events' before the crash are two bangs sent from one [routeOSC] to another. they are listed as 'outlet_bang' and 'pd_defaultbang'. and switching pages gives a bang. so is [routeOSC] having troubles with bangs that do not come together with other messages?

are you sure your page switching isn't causing the crash?

i am sorry if i was unclear or misunderstood you: yes, i am pretty sure that the page switching causes the crash, but only in combination with [routeOSC]. i can reproduce the crash very easily, it happens always in the moment of page switching.

i've tested again to narrow it down: only after a second [routeOSC] is added it crashed with page switching. one [routeOSC] is still ok.

so the crashing patch looks something like that:
...
|
[routeOSC /1 /2]
|
[routeOSC /toggle1 /fader2]

so isn't there some error between the two [routeOSC]?

thanks for the replies - hoping for a solution!

ok, right.

i really don't use this sort of stuff much, but i have a vague memory of having a similar problem when trying to use the mrpeach stuff.

maybe try using [symbol2list] / [s2l] instead of routeOSC? i think it did the same thing, as long as you send the forward slash as a delimiter (just have a look at the helpfile, it should be clear)

does that also crash?
It works well on windows.

great! [s2l] seems to make it work. although it can't handle the / at the beginning of the message. so i came up with quite a complicated treatment of the messages in order to get them into the right shape. it's far from elegant, maybe there are better ways to do this? however, it works. no more crashes!

Gromit: no, the second patch does not crash, but there is no connection to the ipod. when connected with [udpreceive 8000] and [unpackOSC] it crashes again.

thank you both very much for your help!

I understand what was the problem... mine doesn't crash, but tells me this:

* routeOSC: ignoring empty list...

So, TouchOSC sends an empty list with the address "/1" or any page. I don't know why my Pd doesn't crash and yours does... I use Pd-Ext 0.43.4, on Ubuntu 12.04 and Jack.

I reported as a TouchOSC bug: http://hexler.net/forum/viewthread/992/

My version was one from 2008! That's why it worked different.

It was a routeOSC bug and it was fixed in svn, yesterday.

Hi everyone! Sorry if I bump into this topic, but I think I have a solution.
I'm an italian guy and I'm just discovering this awesome world of programming. I'm only at the beginning but I like these stuff!

Back to the topic: I had the same problem and searching into the libraries directory of PD I've tried to use another function to route OSC messages.

The function is called [OSCroute] (just exchanging "route" with "OSC") and does the same as the mrpeach one [routeOSC]. Maybe it belongs to another library, but it works good! No empty list returned!
I though that this problem was already solved but my PD cashed again. So that is the solution i found.

thanks
