I knew there were problems with memory, but not that this was new in 5.

Have you tried disabling memoisation?  It could be that before 5 it was so
broken it didn't work.  Use config.no_memoize().

Otherwise, an example of something (as simple as possible) that shows a big
difference between 4 and 5would help me track down the issue.
