Category: Compiler Group: 6.0 Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: bug ghc --make Initial Comment: Using ghc-6.0 with ghc --make mimico.hs gives: ghc: panic! (the 'impossible' happened, GHC 6.0): coreSyn/coreUtils.lhs: 1188: Non-exaustive patterns in function isCrossDllArg I've done some work to help you finding the cause of the bug, by leaving only 4 (stripped down) files (see attachment). A single line --- the definition of function getInput, in ParsecPrim.hs --- is indicated that, if modified (by writing, say, "getInput=undefined") causes "ghc --make mimco.hs" not to 'panic'. (The bug turned out to appear in Parsec files; seems Daan Leijen didn't use "ghc --make" :-). Hope that helps...

Silly guessing by myself.
