Hello.  I think I've seen other people encounter this problem before, but I wasn't able to find the solution, if there is one.

I have a very large static list of type [[Int]].  It is 128 lists of 128 integers each.  When I try to load the module that defines this list, I get an error:

  ghc: panic! (the 'impossible' happened)
    (GHC version 6.10.1 for i386-apple-darwin):
          linkBCO: >= 64k insns in BCO

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

This happens on both linux and mac os, both ghc-6.8.3 and ghc-6.10.1, and both GHC and GHCi.  Is there anything I can do to avoid this?  Thanks!

Sorry for the inconvenience.  Splitting the list into two modules should avoid it.  Here's the relevant ticket:

Ah, thanks.  In this particular case, I was also able to get it to work by binding each list inside the top-level list like this:

top_level_list = [ list0, list1, list2, list3, list4, list5 ... list127]

list0 = ...
list1 = ...
list2 = ...
...
list127 = ...
