GHC 9.2.5 / 9.4.3 regression: ListLike-4.7.7 test suite is extremely slow when sorting DLists
Summary
ListLike-4.4.7's test suite hangs indefinitely at Testing 2:ListLike:60:sort:14:DList Int
- Bug manifests GHC 9.2.5 and 9.4.3.
- Bug does not happen with 9.2.4 and 9.4.2.
- Bug does not happen with HEAD (or 9.6)
Steps to reproduce
Build ListLike-4.4.7 (sdist from hackage, revision 1) using GHC 9.2.5, 9.4.3, 9.4.2 and GHC 9.2.4 and run the test suite.
The 9.2.4 and 9.4.2 ones will succeed, but 9.2.5 and 9.4.3 will hang indefinitely (I waited for ~2h) at this point in the test suite:
