T18522-dbg-ppr.hs is broken
Compile failed (exit code 1) errors were:
[1 of 2] Compiling Main ( T18522-dbg-ppr.hs, T18522-dbg-ppr.o )
T18522-dbg-ppr.hs:13:1: error: [GHC-61948]
Could not find module ‘GHC.Tc.Utils.Zonk’.
Perhaps you meant
GHC.Tc.Utils.Env (from ghc-9.7)
GHC.Tc.Utils.Monad (from ghc-9.7)
Use -v to see a list of the files searched for.
but as the test is marked fragile, it wasn't updated when zonking was refactored. Now it has no chance to work.
