Hello everyone, The GHC team is happy to announce the second candiate of the 8.0.2 release of the Glasgow Haskell Compiler. Source and binary distributions are available at
http://downloads.haskell.org/~ghc/8.0.2-rc2/
This is the second and likely final release candidate leading up the
8.0.2 release. This release will fix a number of bugs found in 8.0.1
including,
* Interface file build determinism (#4012).
* Compatibility with macOS Sierra and GCC compilers which compile
position-independent executables by default
* Runtime linker fixes on Windows (see #12797)
* A compiler bug which resulted in undefined reference errors while
compiling some packages (see #12076)
* Compatability with systems which use the gold linker
* A number of memory consistency bugs in the runtime system
* A number of efficiency issues in the threaded runtime which manifest
on larger core counts and large numbers of bound threads.
* A typechecker bug which caused some programs using
-XDefaultSignatures to be incorrectly accepted.
* More than two-hundred other bugs. See Trac [1] for a complete
listing.
This release candidate fixes a number of issues present in -rc1,
* #12757, which lead to broken runtime behavior and even crashes in
the presence of primitive strings.
* #12844, a type inference issue affecting partial type signatures.
* A bump of the `directory` library, fixing buggy path
canonicalization behavior (#12894). Unfortunately this required a
major version bump in `directory` and minor bumps in several other
libraries.
* #12912, where use of the `select` system call would lead to runtime
system failures with large numbers of open file handles.
If all goes well we should have a final 8.0.2 release out shortly after
the new year. As always, let us know if you encounter trouble. Thanks to
everyone who has contributed so far!
Happy testing,
- Ben
