Seems similar to the bug reported by Oleg Avdeev on Dec 7, although it does
not seem like the patch provided then solves this problem. Program compiles
with R11B-5 but not with R12B-0.

Problem:
---------

$ erlc test2.erl
test2: function f/1+10:
  Internal consistency check failed - please report this bug.
  Instruction: {bs_put_integer,{f,0},
                               {integer,8},
                               1,
                               {field_flags,[unsigned,big]},
                               {x,0}}
  Error:       {match_context,{x,0}}:


Test program:
--------------
-module(test2).
-export([f/1]).

f(<<"A", H/binary>>) -> <<"B", H>>.
