I have built a really simple block for testing purposes…
When I run it, I get segmentation faults and source diving has
not revealed the problem to me — there's a lot of code there, too
much for me it seems.
Am I doing something so horribly wrong?
The build I'm using from jbuml's git:
* jblum d393bef gruel: put common swig stuff in gruel_common.
