compiled from source with no issues on Mac OS 10.12.2 with XCode 8.2.1. Compiled vector package with it, did some smoke testing of the runtime, seems fine

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
