#7944: GHC goes into an apparently infinite loop at -O2 -------------------------------------+------------------------------------- Reporter: bos | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.9 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash | Test Case: Blocked By: | Blocking: Related Tickets: #5550 #8852 | Differential Revisions: -------------------------------------+------------------------------------- Comment (by amosrobinson): Hmm. So I thought in this case, the is_too_recursive check should stop specialisation after a few runs. The counting of recursive constructors is only going down through applications though: I wonder whether it needs to handle lets, cases, etc? https://github.com/ghc/ghc/blob/master/compiler/specialise/SpecConstr.hs#L18... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7944#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
