Comment:

 Thanks for the report. This reminds me of #867, but that is fixed in 6.6.

 Unfortunately I don't have 8G of RAM, so reproducing this is non-trivial.
 I tried with some smaller examples, but couldn't reproduce it. If anyone
 has a smaller example then please let us know, but of course it's possible
 that it is only when >2G of RAM is being used that problems happen.


 Thanks

 Ian
