Perf/compiler/T3294 has very different max_bytes_used when BINDIST=YES than without. See below.
I don't know why. I don't know whether it matters. Maybe it's just the moment that GC strikes. But it's uncomfortable to have such an erratic test failure.

Hmm, my first (inplace) run was 41241960, but since then I'm reliably getting 38586080 for inplace, and 38904040 for BINDIST=YES. I'm not sure why they are different at all; perhaps it's just due to the size of the package.conf or something. -- Ian Lynagh, Haskell Consultant Well-Typed LLP, http://www.well-typed.com/
