- Start 'Emacs -Q' to visit a 'big' source code file that is revisionned
  on Subversion 1.6.17 (r11280011).
- Use 'C-x v g' to run vc-annotate to annotate the file.
- When the file size is over a (around) limit of 64KiB, only the lines
  corresponding to about 64KiB characters are annotated as they should.
  The lines after that limit are not annotated.  The command does not
  fail and does not report any problem.  It's just that it does not
  annotate the complete set of lines.

If I try 'svn blame' on that file inside a bash shell running in the
Linux terminal, all lines are annotated.  If I start a shell inside
Emacs (with M-x shell) and I run the 'svn blame' command inside that
shell, then all lines are annotated.

If the file is small, all lines are annotated by vc-annotate.
But when the file is large (over about 64KiB) then the end of the files
are never annotated.

This happens on Subversion.
No crash.
-----------------------------------------------

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    'bt full' and 'xbacktrace'.
