--exact-conf complains about unspecified flags, even when they're default and/or explicitly given

The exception was:
ExitFailure 1

It doesn't actually make any difference here whether I add the --flags="semigroups tagged", the error is the same without that. (Which isn't completely surprising because the flags should anyway be on by default, what's surprising is that, allegedly, they aren't on.)

The exception was:
ExitFailure 1

This originally happened when I (for the first time) tried to new-build one of my packages instead of old-style installing it, namely free-vector-spaces. This attempt can't have broken any global configuration that now causes the issue even with standard install for distributive and bytes, can it?

$ cabal new-build -v

[leftaroundabout]

The offending commit appears to be 0a1b9df.

No, it's actually 69e496a.
