Title:
  sed segfaults on L command with long address lengths

Status in sed package in Ubuntu:
  Triaged

Bug description:
  To reproduce, run:
  sed 'L222222' <<<d

  These do not segfault:
  sed 'L22222' <<<d
  sed 'L2222222222222222222222222' <<<d

  I do not have any expected behavior for this as it was just found by the fuzzer AFL.

  System is AMD64
  Distributor ID:	Ubuntu
  Description:	Ubuntu 14.04.1 LTS
  Release:	14.04
  Codename:	trusty
