5. Release notes for version 8.8.3¶
GHC 8.8.3 is a minor release intended to fix regressions and minor bugs in the 8.8.1 and 8.8.2.
5.1. Highlights¶
- Fix a compiler panic due to over-zealous eta reducation (Issue #17429).
- Fix a linker crash on Windows (Issue #17575).
- Fix missing source notes in imported unfoldings when
-gis used (Issue #17616). - Fix bootstrapping with GHC 8.8 (Issue #17146).
- Bump
directorysubmodule to 1.3.6.0, fixing Issue #17598.
5.2. Known issues¶
A long-standing bug (Issue #16893) which can cause some applications of
unsafeCoerceto segmentation fault is only partially fixed in this release. This release only avoids this issue in the uses ofunsafeCoerceinData.Typeable.Internal, which was the proximate cause of Issue #16893.However, it is possible that this bug could manifest in user-code using
unsafeCoerceto perform dynamic type checks. See the ticket for details.
