Re: [PD] [hid] crashing with segmentation fault

7 Jan 2006

      Are you able to narrow down which device is causing it?  Looks like

syn_report messages are the culprit.  I don't have a device that

outputs syn_report events (IIRC).
I'll look at this today.

Hi Hans, hi list,
I just got back to trying to make [hid] work on my laptop and I still

can't...
[hid] is the latest from CVS (Friday, January 6th 2006) and still

gives segmentation faults.
My machine is a PC running Debian unstable with 2.6.14.
Here's more detail:
I have 3 HID peripherals on the machine:

/dev/input/event0 :: Keyboard
/dev/input/event1 :: Touchpad
/dev/input/event2 :: USB Mouse

"$ hexdump /dev/input/event1" doesn't output anything so I assume the

touchpad doesn't send info well. Let's forget about that for now.
"$ hexdump /dev/input/event0"
"$ hexdump /dev/input/event2"
Both output hex. dataflow.
The output from [print( sent to [hid] compiled in debug mode for the

keyboard is printKeyboard.txt. printTouchpad.txt and printMouse.txt

are the outputs from the 2 other peripherals.
The 2 other files (printSegFaultKeyboard.txt and

printSegFaultMouse.txt)  is the stderr from the two peripherals that

make [hid] crash. Touchpad doesn't seem to send anything.
I suspect the problem being similar to what Gerda experienced in:

http://lists.puredata.info/pipermail/pd-list/2005-08/030339.html
Do you know where the problem may come from?
Do you need more output from anything?
