Thanks Ben, this is great! Installing the binary on the Mac results in the following minor problem: /usr/bin/install -c -m 644 docs/users_guide/build-man/ghc.1 "/usr/local/share/man/man1" install: /usr/local/share/man/man1/ghc.1: No such file or directory make[1]: *** [install_man] Error 71 make: *** [install] Error 2 The error message is a bit confusing as the file does exist. It is easily resolved by rm /usr/local/share/man/man1/ghc.1 I believe I encountered the same problem on ghc 8.0.1 rc1 Thanks George On Fri, Nov 25, 2016 at 6:39 PM Ben Gamari wrote:

Hello everyone,

The GHC team is happy to (finally!) announce the first 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-rc1/

This is the first of what will hopefully be only two release candidates leading up the final 8.0.2 release. This release will fix a number 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.

Unfortunately there is one known bug (#12757) which can result in runtime crashes which is still lurking in -rc1. This will be fixed in -rc2, which will be released in about a week.

As always, let us know if you encounter trouble. Thanks to everyone who has contributed so far!

Happy testing,

- Ben

Thanks Ben! When testing, I found that a type checker regression from 7.10 to 8.0 that I thought/hoped was resolved is in fact still present in this release candidate. I filed a new bug: https://ghc.haskell.org/trac/ghc/ticket/12885 It originally seemed the same as #12175. But unfortunately, although that problem is resolved in 8.0.2-rc1, this one is still around (though they may still be related). Thanks, -Judah On Fri, Nov 25, 2016 at 2:38 PM, Ben Gamari wrote:
