Yes, but you're using FXRuby which is a C component.

Since you haven't provided a sample code that shows the segmentation
fault. I must tackle all the possible issues, including the spawn of
threads by FXRuby and using Ruby-based callbacks.

So, Ruby green threads are OK, as long you don't mix them with real
threads. In your post you mention "4 different threads"

We are just guessing all due your lack of code.
