Comment (by harpocrates):

 Alright. Without really having looked at the contents of commits, I can
 say something about the behaviour of certain ranges.

   * 4631ceb261cb08756b955c6b495d5e719d35ab62 is the last commit which
 builds and doesn't crash when compiling some TH
   *
 8f0b2f5eadf0fcb47c581907205a9db686214a69-df7ac37d43bdbabbde9b09344f9425e8e5a879ff
 don't build at all (`No rule to make target 'libraries/integer-
 gmp/include/HsIntegerGmp.h'`)
   *
 f6cf4001574e789865d25f89b362a04ef1ca3df4-affdea82bb70e5a912b679a169c6e9a230e4c93e
 (and probably later) build but crash when I try to compile anything that
 involves TH

 In terms of the way in which the crash happens: I've run into both
 segfaults and panics.

 Since the possibly offending commit bumps Cabal, I'm not sure if this
 isn't just another manifestation of
 https://github.com/haskell/cabal/issues/5222.
