[developers] Error when generating wordforms

[Ann Copestake]

I'll have a look at the code to see if I can see anything suspicious but it 
won't be till next week at best - things are very busy.  My suspicion is that 
the code is doing a backdoor unification or something like that and that the 
dag pool mechanism fails to cope.  I suppose there could be an interaction 
with the garbage collector.

Can you recompile the code?  It might just be worth trying it with different 
safety/size/speed settings in the compiler.
