#8333: The impossible happened with TH + -fno-omit-interface-pragmas -------------------------------+------------------------------------------- Reporter: errge | Owner: Type: bug | Status: patch Priority: high | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Easy (less than 1 hour) Type of failure: GHCi crash | Blocked By: Test Case: | Related Tickets: Blocking: | -------------------------------+------------------------------------------- Changes (by klao): * cc: mihaly.barasz@… (added) * difficulty: Unknown => Easy (less than 1 hour) * status: new => patch Comment: The attached patch contains an obvious easy fix. Another approach would be to change `TidyPgm` to remove the breakpoints even if -fno-omit-interface-pragmas is on. But, I don't see clearly what other consequences would that have. There was obviously a path to this panic from GHCi, but maybe it could also be triggered by someone using the GHC API directly. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8333#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
