I am having trouble with the EEGLab import of BCI2k data. The import works with all applications i have written so far except my most recent one. I dont think i did something different in this application regarding setting state variables.
Still, when i try to import them in matlab i get a segfault with this stack trace:

...I guess i did something in my application module that leads to inconsistent data. Do you have any hints what type of coding-error could lead to this behaviour? I assume it must have something to do with setting certain state variables.
The recording was done in this way:
(tested with Signalgenerator and gUSBAmp as signal source)
pressed start
let it run a few seconds
pressed stop
quit
