GHC 8.8.2-rc1 is now available


#1

Hello everyone,

The GHC team is proud to announce the first release candidate of GHC
8.8.2. The source distribution, binary distributions, and documentation
are available at the usual place.

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 (Trac #17480)

  • A typechecker bug (#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 (#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!

Cheers,

  • Ben
