#3098: undefined bug
---------------------------------+------------------------------------------
Reporter: rheineke | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.10.1 | Severity: normal
Keywords: undefined impossible | Testcase:
Os: MacOS X | Architecture: x86
---------------------------------+------------------------------------------
I coded the PrettyStub.hs file as shown in the Real World Haskell, page
119 and loaded it into ghci. I then proceeded to follow the examples on
page 120:
ghci>:load PrettyStub
[2 of 2] Compiling Main ( PrettyStub.hs, interpreted )
Ok, modules loaded: SimpleJSON, Main.
ghci>:show modules
SimpleJSON ( SimpleJSON.hs, SimpleJSON.o )
Main ( PrettyStub.hs, interpreted )
ghci>:type undefined
undefined :: a
ghci>undefined
*** Exception: Prelude.undefined
ghci>double 3.14
ghc: panic! (the 'impossible' happened)
(GHC version 6.10.1 for i386-apple-darwin):
loadObj: failed
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
And now I'm here.
