M-/ in edit replacement string

M-/ in edit replacement string

[Kevin Spiteri]

In GNU Emacs 21.2.1 (i386-msvc-nt5.0.2195)
  of 2002-03-19 on buffy
configured using `configure --with-msvc (12.00)'
Important settings:

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In a buffer containing the following two lines only:
abc
def
run query-replace to "abc" to "ghi". When there is the query,
delete the replacement, type d, and press M-/ <return>.
An error message is given:
perform-replace: Args out of range: 26, 27
When using M-/ in larger buffers, there is no error message, but
there is some unexpected behaviour.


Relevant input:
C-x b h e l l o <return> a b c <return> d e f <return>
M-< M-% a b c <return> g h i <return> e <M-backspace>
d M-/ <return>

Relevant messages:
perform-replace: Args out of range: 26, 27

This does not seem to fail for me in the current development Emacs
sources, so I think the bug was fixed.  Or else other changes covered
it up somewhat.

Would you like to try running the latest development Emacs
from CVS on savannah.gnu.org, and see if you can make some
variant of this fail?
