Thanks for reporting that bug, which I recently introduced. I installed the 
attached to fix it.

Applied it, ran the new version. Works fine (I think)
when compiling using 'clang-cl.exe',
But with MSVC's 'cl.exe', I often get:
  diff.exe: memory exhausted

(on directory branches with approx. > 7000 files)

From where the allocation fails, I've no idea since Gnulib is so
unfriendly telling where this occurs. Is there really no
xmalloc_die() with some more useful messages than this? Yikes!
