#14043: GHC.Stack.callStack throws exception -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.4.1 Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): The problem appears to be that `callStack` is defined directly in terms of `popCallStack`, which fails on an empty stack. Presumably we should just return an empty stack in this case. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14043#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
