Subject: [PATCH] Fix asan build

Summary:
The array-bounds checker in gcc complains that r could be -1 after leaving CHECK_ERR in ASAN mode. Switch to DCHECK to avoid this possibility. The code was not initially compiling; now it does.

Error from gcc:
  array subscript is below array bounds [-Werror=array-bounds]
