hard crash when calling send_command() with eyelink

dschreij commented 10 years ago

pygaze commit afef6d913357ca6b8e996747ee1f1b54dbce4e45 Windows 7; OpenSesame 2.8.3 Occurs on EyeLink CL/1000 and EyeLink 2000

When the pygaze_eyetracker.send_command() is called with EyeLink as the eyetracker type, the experiment crashes with a segmentation fault (thus quite serious). It does not depend on the contents you pass to send_command(). I've tried with various strings and all cause the crash.

Hi Daniel,

For me this works fine on Windows XP. Could you try to trace this down further? send_command() is just a wrapper around this:

import pylink
pylink.getEYELINK().sendCommand("my message")

What happens if you send commands directly with PyLink? It would be weird if calling send_command() always crashes always, because it is heavily used internally.

Hi Sebastiaan,

I finally got around testing this. It also crashes when you call the sendCommand function directly through pylink. Weirdly enough, this does not happen when using the old eyelink plugins...

I tested this on Windows 7 with the latest snapshot of pygaze. This is the error output

 Problem Event Name:    APPCRASH
  Application Name: python.exe
  Application Version:  0.0.0.0

Not that this will probably mean anything to you, but just for the sake of completeness. eyelink_core.dll appears to be the culprit.

The pylink version appears to be 1.0.0.43. I might try upgrading (if it's possible to find a newer version. the SR forum is quite a mess)
