Segmentationfault

OK, so you are still getting a segfault.

I think this must be due to an error in your driver or database.

Can you explain why you are writing your own driver rather than using StreamDevice?

What happens if you temporarily remove PINI=YES from that ao record?

Segmentationfault

I know, its a bit of improvement, but...

gdb tells me:

Program received signal SIGSEGV, Segmentation fault.

and thats exactly the same place as before.
