You should be free to call this at any point. We did extensive work to recover memory from dead instances and
this could be a bug resulting from it. If we had a test code then we could debug.

Thanks; there is definitely a bug and it is to do with “named” instruments. It appears that if you use
numbers only, it is OK. 
I’ll try to get to the bottom of it.

Ok, I think I’ve stabilised this situation and named instruments are not crashing on
recompilation (at least they pass your test). I need to go back and assess the 
situation a little more, because I want to check that we are recovering as much
memory as possible. But for now, the code in GIT should work.
