[erlang-bugs] Compiler internal consistency check failed

[Bjorn Gustavsson]

The pattern matching is too complex. R11B-2 gives the following,
clearer error message:

bug: function run/0+1619:
  An implementation limit was reached.
  Try reducing the complexity of this function.

  Instruction: {get_list,{x,1018},{x,1023},{x,1024}}

To reduce the complexity, you could first divide the list into
two or more parts, and then match the parts separately.
