bug#36696: 26.2; query-replace error

[Theodore Ehrenborg]

How to make this bug:
Type emacs -Q
Use C-x C-f to open a new file called test.tex
Type the following three lines in test.tex:
\foo
foo
foo
(The first line is '\foo', not 'foo')
Then go to the beginning of the file with M-<
and use M-% to begin query-replace
Try to replace 'foo' with 'foo'.
When prompted for the first line,
type 'y' to replace.
Then emacs returns an error:
Args out of range: #<buffer test.tex>, 0, 1

I'm using the most recent installation of MacTex and emacs.
Both were installed with Homebrew.

Thank you,
Theodore Ehrenborg
