#12403: Template Haskell boxes unboxed tuple types when reifying them -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Type: bug | Status: merge Priority: normal | Milestone: 8.0.2 Component: Template Haskell | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: th/T12403 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2405 Wiki Page: | -------------------------------------+------------------------------------- Comment (by Ryan Scott ): In [changeset:"acdbd16ffca4f13cfae6eeed045a6fc5969adee2/ghc" acdbd16f/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="acdbd16ffca4f13cfae6eeed045a6fc5969adee2" Move #12403, #12513 users guide notes to 8.2.1 release notes The changes in #12403 and #12513 subtly changed the behavior of Template Haskell reification and splicing. While the old behavior was certainly buggy, it's possible that there's code in the wild that depended on the old behavior to work. To err on the side of caution, I'll postpone these changes to GHC 8.2.1 instead of having them merged into GHC 8.0.2. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12403#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
