#11106: Optimizer changes behavior in 7.10.3 -------------------------------------+------------------------------------- Reporter: dsf | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- The repository at https://github.com/ddssff/ghcbug contains a four module package that works when compiled with -O2, but fails when compiled with -O2. The cabal file builds working and failing executable. One of the modules has OPTIONS_GHC -O0 in the header, so the bug is related to mixing modules with different optimization levels. Other than that, I have little idea what is going on. The bug was present in 7.10,2, and is definitely still present in 7.10.3-rc1. I doubt it has been fixed since then. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11106 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
