Dear GHC developers, I am preparing a bug report for the compiler of ghc-6.8.0.20070928-src: ------------------ GBasFld_.hs:387:45: Warning: Defined but not used: `t' ghc-6.8.0.20070928: panic! (the 'impossible' happened) (GHC version 6.8.0.20070928 for i386-unknown-linux): initC: srt_lbl Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug ------------------ This happens in the middle of the DoCon-2.11 `make'. Can you wait with ghc-6.8.1 ? Another point: the module Char_ exports several instances, and the module DPrelude has `module Char_' in its export list, and ghc-6.8.0.20070928-src reports that this latter decl "exports nothing". Probably, it must report "exports nothing, besides maybe, some instances" ? Regards, ----------------- Serge Mechveliani mechvel@botik.ru
