Rob, Thanks for that and for cutting it down to something manageable. As a result I've been able to track down and fix the problem. Let me know as and when you find anything else.
Regards, David

? I am getting a segfault somewhere in the ProofPower parser generator. I will report again when I have isolated that.
To the list of three issues in my previous e-mail, I can now add:
- In some circumstances a function call can lead to a segfault.
I?ve attached a short extract from the parser generator code that demonstrates the problem. If you execute the body of the function empty_non_terminals interactively with the parameter bound to the test data, then nothing goes wrong. If you call the function with the test data as parameter (as on the last line of the attached file) you get a segfault.
Regards,
Rob.
