I think it's because the system dlopen runs the sections in a different order than modern dlopen (which is the order the test expects). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8458#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I suppose there are a few things we could do. Probably the easiest thing to do is relax the test and warn users that GHCi's static loading behavior may differ from the dynamic loading behavior on certain platforms (code with both ctors and init_array ought to be quite rare). Could be a nasty gotcha if it does matter, though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8458#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
