Hello everyone, The GHC team is very pleased to announce the third candidate of the 8.2.2 release of the Glasgow Haskell Compiler. Source and binary distributions are available at
https://downloads.haskell.org/~ghc/8.2.2-rc3/
This is the third and last of three release candidates leading up the
final 8.2.2 release. This release fixes approximately fifty bugs present
in 8.2.1. These most notably include,
* A correctness issue resulting in segmentation faults in some
FFI-users (#13707, #14346)
* A correctness issue resulting in undefined behavior in some programs
using STM (#14171)
* A bug which may have manifested in segmentation faults in
out-of-memory condition (#14329)
* clearBit of Natural no longer bottoms (#13203)
* A specialisation bug resulting in exponential blowup of compilation
time in some specialisation-intensive programs (#14379)
* ghc-pkg now works even in environments with misconfigured NFS mounts
(#13945)
* GHC again supports production of position-independent executables
(#13702)
* Better error messages around kind mismatches (#11198, #12373, #13530,
#13610)
See [1] for the full list.
Release candidate three contains only two patches not present in -rc2
but fixes a packaging issue which lead to unintentional downgrading the
process and Cabal libraries.
As always, please report any issues you encounter.
Happy testing,
- Ben
