Finally got it.
In the end the problem wasn't in the list work at all. Way earlier in the program, I'd allocated memory for an array [1..x], then accessed it as [0..x]. On freeing the memory, I guess something funny was set up in the memory manager that came back to bite me way later.
So... is there a compiler option I could have set that would have told me about this illegal memory access?
well, now perhaps I can sleep. Toby
