Comment:

 It turns out this is a result of the latest XCode update, which broke
 `nm`. Specifically, the new `nm -P` outputs decimal instead of hex which
 causes GHC to set `mAX_SPEC_SELECTEE_SIZE = 21` instead of `15`.

 The fix is to `./configure --with-nm=$(xcode-select
 -p)/Toolchains/XcodeDefault.xctoolchain/usr/bin/nm-classic`.
