Hi!
I experience this bug today as well.
Attached is a Pd-patch that simulates this crash caused by the message
TouchOSC is sending if page is turned (although this can be changed in
the TouchOSC editor!).
This is the gdb output:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000000
0x045f1c59 in routeOSC_list (x=0x5e5990, s=0x0, argc=0, argv=0x0) at
routeOSC.c:410
410 if (argv[0].a_type == A_SYMBOL) routeOSC_doanything(x,
argv[0].a_w.w_symbol, argc-1, &argv[1]);
I attached an easy fix for routeOSC.c
So either rebuild routeOSC with the fix or change the message TouchOSC
is sending on page turn.
(This is done by deactivating the auto checkbox below Page, Name and OSC)

It sounds like you have two issues: one is that the new external
crashes Pd as soon as it is instantiated, the other is that some OSC
messages do the same thing when [routeOSC] is involved.
For the second thing, just use
[udpreceive]
|
[unpackOSC]
|
[print]
and switch pages to see what raw message is being sent.
For the first thing, make a new patch and put a [routeOSC] in it and
see what the console prints.
But then again you don't seem to be able to start Pd at all from the
console. Is that correct?

Thanks, Martin. I compiled it and test it. Again, in UbuntuStudio
12.04.3, it makes PureData crash. There's no message, it just crashs.
Is anything I could do to help to avoid that? How could I debug it?
In the other hand, I'm having troubles to launch Pd from console (to see
if any message is there)... it can't open my patch. So, I'm writting
another mail to list.

I just downloaded complete PureData from svn... but I want to
compile
only your externals. Is that possible? I think so... how?
From trunk/externals type
make mrpeach
or
make mrpeach_install
(which doesn't actually install the files, it puts them in
externals/build/lib/pd-extended/extra)
Martin
Thank you.

Martin Peach, I read somewhere that changing pages in
TouchOSC
makes Pd
(or Pd-Ext) to crash. My Pd-Extended doesn't crash, but
this
error is
shown: "* routeOSC: ignoring empty list…".
That doesn't happen here. There is no such message in the
source code.
Maybe you have an older version of routeOSC? The OSC
specification
allows empty messages, and [routeOSC] should output a bang
if it
routes such a message.
Older versions of [routeOSC](before March 2012) didn't work
properly, so you probably just need to find a more recent
one or
build it from svn.

Today, I've installed Ubuntu Studio 12.04.3 (with
lowlatency
kernel). It
seemed that it was a good distro for my use... but
switching
pages DOES
make Pd-Extended to crash. I reported-suggested this in
this thread:
http://hexler.net/forum/__viewthread/992/
<http://hexler.net/forum/viewthread/992/>, where I
wrote some
other info,
maybe usefull.
The config where it doesn't crash:
/Ubuntu 12.04, Kernel 3.2.0-49-generic, Pd-Extended
0.43.4 (download
from PPA as the Pure Data page says), jackdmp
1.9.8...//
/
The other config:
/Ubuntu Studio 12.04.3, Kernel 3.2.0-51-lowlatency,
same Pd-Extended
version, Jack that came with UbuntuStudio (don't know
wich version)/
Any other information that could be useful to fix this?
Like I
wrote in
the thread, I suggested TouchOSC that it should send
non-empty
lists.
But, TouchOSC is closed-code... so, there's no easy
feedback.
