Are you _sure_ that's what you typed?  ;-)

There, it looks like you are trying to replace "foo" by "a".  I'm
interested in the (invalid) arguments 0, 1 passed to
buffer-substring-no-properties.  I suspect that these are derived from
the "match-data" for a string, in particular for the string "a".

Could you please repeat the bug scenario, but this time try to replace
"foo" by "bar".  I predict you will then get the error message

    (args-out-of-range #<buffer test.cc> 0 3)

since the replacement string will then be 3 characters long.

If that does indeed happen, it would be a very strong clue as to the
underlying bug.  Please try it as above, and post the backtrace here.
Thanks!

I think, I hope very strongly, that the -Q in emacs -Q will prevent any
packages being loaded.  Otherwise we have a problem in the Emacs core.
