[Gtk-sharp-list] Crashes at random spots

[Eric Albright]

Hi,

We have been experiencing crazy random crashes that give us one of the 
messages: "Attempted to read or write protected memory. This is often an 
indication that other memory is corrupt." or "Object reference not set 
to an instance of an object.". The stack indicates that it is trying to 
destroy GTK objects. Our program dynamically generates a form based on 
the data underneath and it consistently happens while iterating through 
records. I tried to reproduce this on my machine at home and was unable 
to which then led me to believe that perhaps there was a threading 
problem since our machines at work are dual core machines.

I thought perhaps it had to do with interaction with the garbage 
collector on a different thread and so I set gcConcurrent=false in the 
app.config, but this hasn't solved the problem.

Anyone have any pointers or ideas?

Thanks,

Eric
