What steps will reproduce the problem?
1. Copy with :o-support from the input link to an impasse substate.
2. Change what is on the input link, causing the substate to retract.
3. reinit.
4. Go to step 1.
There may be extra steps involved, unfortunately. I'm going to hold onto
my agent capable of causing the problem. It is currently too large / too
dependent on other things to upload.
What is the expected output? What do you see instead?
I expect it not to crash, but it does.
