#14218: GHC.Stack.HasCallStack not compatible with constraint synonyms -------------------------------------+------------------------------------- Reporter: ntc2 | Owner: (none) Type: bug | Status: merge Priority: normal | Milestone: 8.2.2 Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: | typecheck/should_run/T14218 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by simonpj): * testcase: => typecheck/should_run/T14218 * status: new => merge * milestone: => 8.2.2 Comment: Thanks for reporting this bug. It is a rather insidious and long-standing one. The test I added has two cases, one for vanilla implicit parameters and one for call-stacks. Could consider merging this to 8.2, but I doubt it'll affect many people. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14218#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
