Issue created Apr 03, 2011 by danw@trac-danw

internal error: update_fwd: unknown/strange object -1206004376

When I compile my parallel program with the following command line:

ghc -O2 --make -threaded Main.hs

Then run the program with the following command:

  1. /keno +RTS -N -M8G

The program crashes with the following error: keno: internal error: update_fwd: unknown/strange object -1206004376

(GHC version 6.12.3 for x86_64_unknown_linux)

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug

If the heap were too small then I would expect the runtime system to tell me that the heap is too small rather than blow up like this.
