#3801: ghc-6.10.4: internal error: PAP object entered
-------------------------+--------------------------------------------------
Reporter: patrikja | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.10.4 | Keywords:
Os: Linux | Testcase:
Architecture: x86 | Failure: Runtime crash
-------------------------+--------------------------------------------------
Running the compiled code for a simple program using WX Haskell +
QuickCheck gives "internal error: PAP object entered". (I cannot submit
the source code openly right now because it is a solution to course
homework in the course I'm teaching Jan-March, but I could send it to
whoever is assigned to this bug. Just ask patrikja+ghc AT gmail .)
The error appeared after adding a dependency on QuickCheck (in base) and
the Control.Monad.Writer (in mtl) - before that it compiled and worked
fine.
Searching the trac history most PAP object entered seem to refer to
http://hackage.haskell.org/trac/ghc/ticket/1372 but I'm not sure how to
make sure no "mismatched library versions" are around. I'd be happy to
rebuild / reinstall my whole cabal library setup if there is an easy way
to do that.
Another clue may be the libstdc++.so.6 warning I get after each compile -
see below. (That warning has been there also for all the working versions
of the code so I'm not sure if it is relevant here.)
