#1186: GHC as a library panic on loading second module
---------------------------------+------------------------------------------
Reporter: ArthurVanLeeuwen | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: GHC API | Version: 6.6
Severity: normal | Keywords:
Difficulty: Unknown | Testcase:
Architecture: powerpc | Os: Unknown
---------------------------------+------------------------------------------
Given the following two modules:
{{{
module GHCLibTest where
import GHC
import PackageConfig
import DynFlags
main = do session <- newSession JustTypecheck (Just
"/usr/local/lib/ghc-6.6")
f <- getSessionDynFlags session
f' <- parseDynamicFlags f ["-isrc","-ilib","-ilib/DData
","-fglasgow-ex
ts","-package wx"]
setSessionDynFlags session (fst f'){hscTarget = HscInterpreted}
let preludeModule = mkModule (stringToPackageId "base")
(mkModuleName
"Prelude")
setContext session [] [preludeModule]
t <- guessTarget "src/Main.hs" Nothing
addTarget session t
load session LoadAllTargets
}}}
and
{{{
module OtherModule where
import Data.List
type Nummer = String
data Beademing = HFO | CPAP | IPPV | Geen
deriving (Show, Read, Eq)
data Bloeddruk = Hypertensie | Hypotensie | TensieNormaal
deriving (Show, Read, Eq)
data Partus = PartusTeVroeg | PartusNormaal
deriving (Show, Read, Eq)
}}}
the following results:
{{{
harlan:~/Werk/dss/software/ghclib arthurvl$ echo "main" | ghci -package
ghc ghclibtest.hs

Ok, modules loaded: OtherModule, GHCLibTest.
*GHCLibTest> ghc-6.6: panic! (the 'impossible' happened)
(GHC version 6.6 for powerpc-apple-darwin):
lookup_dfun main:OtherModule.$f1{v r5ig} [lid]
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
*GHCLibTest> Leaving GHCi.

This does not just occur for this recursive case, but
also for cases where the main module is from some
completely different program.
