Sorry, only just saw this. -fghci-leak-check is a new flag I added to prevent regressions of the space leak that was fixed in https://phabricator.haskell.org/D4659

If you're seeing errors from this, then we should fix them. Could you open a ticket and assign to me please?

Cheers

Simon

One thing I forgot to mention is that these test failures only seem to occur with the `quick` build flavor, and I couldn't reproduce them with ./validate. Is -fghci-leak-check expected to have different behavior if stage-2 GHC is built without optimization?
