Release notes for version 8.8.2
GHC 8.8.2 is a minor release intended to fix regressions and minor bugs in the 8.8.1.
- A bug (:ghc-ticket:`17088`) in the compacting garbage collector resulting in
segmentations faults under specific circumstances. Note that this may affect
user programs even if they did not explicitly request the compacting GC
(using the :rts-flag:`-c` RTS flag) since GHC may fallback to compacting
collection during times of high memory pressure.
- A code generator bug (:ghc-ticket:`17334`) resulting in GHC panics has been fixed.
- A bug in ``process`` causing builds using ``hsc2hs`` to fail
non-deterministically on Windows has been fixed (:ghc-ticket:`17480`)
- A typechecker bug (:ghc-ticket:`12088`) resulting in programs being
unexpectedly rejected has been fixed.
- A bug in the implementation of compact normal forms resulting in segmentation
faults in some uses of :ghc-ticket:`17044` has been fixed.
- A bug causing GHC to incorrectly complain about incompatible LLVM versions
when using GHC 7.0.1 has been fixed.
Known issues
- A long-standing bug (:ghc-ticket:`16893`) which can cause some applications
of ``unsafeCoerce`` to segmentation fault is only partially fixed in this
release. This release only avoids this issue in the uses of ``unsafeCoerce``
in ``Data.Typeable.Internal``, which was the proximate cause of
However, it is possible that this bug could manifest in user-code using
``unsafeCoerce`` to perform dynamic type checks. See the ticket for details.
