Just to test this out, I created a 4.7G file of just '\n' and I see
exactly the behavior described.  I then tried a simple change (attached,
based on 7.4.728) to have Vim use LONG_MAX for MAXLNUM rather than the
hard-coded value.  Now Vim didn't stop loading the file partway through,
but it did get killed by the OOM killer after taking up 14G of RAM.

Title:
  Vim has 32-bitlimits; annoying on really large files and 64-bit
  machine

Status in vim package in Ubuntu:
  Confirmed

Bug description:
  I have a program that I'm debugging.  It generates enormous log files
  which I need to peruse.  I use vim as the tool of choice ordinarily,
  but vim stops loading the text when it reaches line 2147483647.  That
  sounds familiar.

  It gives no hint of what's wrong, so I tried several times.  Then I
  noticed the line number of the last line it would show.

  This makes vim useless for the purpose.
  I regard the limit as an implementation limit which I hope you will extend.  I regard the failure to report as a bug which ought to be fixed.  I hope you agree.

  Requests:
   - On a 64-bit machine it would be nice if that were a 64-bit long long.
   - On any machine it would be nice if vim noticed it had failed and reported that fact.
