GHC HEAD: cannot bootstrap HEAD with HEAD
The first invocation of a freshly built inplace/bin/deriveConstants
hangs when I am bootstrapping HEAD with HEAD.

There are only a few revisions in between. Notably:
commit 8a506104d5b5b71d5640afc69c992e0af40f2213

Major Overhaul of Pattern Match Checking (Fixes #595)
...
Incidentally there are a few known performance regressions from that commit, so maybe the bootstrap process is bitten by it.
I am not sure whether deriveConstants
really hangs or just takes ages to complete.
