GHC 8.8.2 released

bgamari - 2020-01-16

The GHC team is proud to announce the release of GHC 8.8.2. The source distribution, binary distributions, and documentation are available at downloads.haskell.org. Release notes are also available

This release fixes a handful of issues affecting 8.8.1:

A bug (#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 -c RTS flag) since GHC may fallback to compacting collection during times of high memory pressure.

A code generation bug (#17334) resulting in GHC panics has been fixed.

A bug in the process library causing builds using hsc2hs to fail non-deterministically on Windows has been fixed (#17480)

A typechecker bug (#16288) 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 (#17044) has been fixed.

A bug causing GHC to incorrectly complain about incompatible LLVM versions when using LLVM 7.0.1 has been fixed (#16990).

As always, if anything looks amiss do let us know.

Happy compiling!
