Although it does look like a bug, you missed the warning:

  /tmp/test.erl:12: Warning: variable 'Problem' exported from 'if' (line 4)

So instead try:

   ,----
   | error(Test) ->
   |     Problem = if
   |                   Test == 1 ->
   |                       1;
   |                   Test == 2 ->
   |                       2
   |               end,
   |     Dummy = 1,
   |     OKbin = <<Test:7, Dummy:9>>,
   |     MyBin = [<<Test:7, Problem:9>>, OKbin].
