 * milestone:  1.3.4 => 1.2.22


Comment:

 I've split `decode_length()` into 32 and 64 bit variants, and the
 appropriate one should now get called in each case, which should fix this.

 That's in git master [24c7867693cf5746eab0e1cc50546b3e1bfc8332], which
 will be in 1.3.4.

 We already have a test that total doclength > (1<<32) works, but actually
 this case is problematic only once it exceeds (1<<35), and the existing
 test case didn't cause that to happen, so I've extended it to provide a
 regression test:

 466ae43450e238ce76b0f73fdd27e7c0bfad100a

 It would be useful to have confirmation that your total document length is
 > (1<<35) (34,359,738,368 i.e. 34 billion and some), as if it isn't then
 the bug I've fixed isn't actually the one you hit.

 We should also backport this.
