20% regression in max_bytes_used for T1969
This is 20% worse:
=====> T1969(normal) 1 of 1 [0, 0, 0]
cd "./T1969.run" && "/data/users/smarlow/ghc/inplace/test spaces/ghc-stage2" -c T1969.hs -dno-debug-output -no-user-package-db -rtsopts -fno-warn-missed-specialisations -fshow-warning-groups +RTS -G1 -RTS +RTS -V0 -tT1969.comp.stats --machine-readable -RTS
max_bytes_used value is too high:
Expected T1969(normal) max_bytes_used: 15017528 +/-15%
Lower bound T1969(normal) max_bytes_used: 12764898
Upper bound T1969(normal) max_bytes_used: 17270158
Actual T1969(normal) max_bytes_used: 18071064
Deviation T1969(normal) max_bytes_used: 20.3 %
*** unexpected stat test failure for T1969(normal)
One of these patches is the culprit, but I can't tell from the build logs because the build was broken between these two points:

Implement unboxed sum primitive type
The patch immediately preceding this sequence does not have the failure: https://phabricator.haskell.org/rGHC83e4f49577665278fe08fbaafe2239553f3c448e (follow the link to the build)
and the final patch in this sequence *does* have the failure: https://phabricator.haskell.org/rGHC6a4dc891fa7a8024d8f9f03b98ad675ff5fcbd91 (along with an improvement in T9675)
