sed-4.0.7 bug

[Bruno Haible]

Hi,

Here is a case where GNU sed 4.0.7 produces an incorrect result.

$ sed --version | head -1
GNU sed Version 4.0.7
$ sed -n -e 's,^.*/CreationDate 
(D:\([0-9][0-9][0-9][0-9]\)\([0-9][0-9]\)\([0-9][0-9]\)\([0-9][0-9]\)\([0-9][0-9]\)\([0-9][0-9]\).*$,ctime:
 \1-\2-\3 \4:\5:\6,p' pressQA4.pdf 

No output!

But with a different sed program:

$ /usr/bin/sed --version | head -1
GNU sed version 3.02.80
$ /usr/bin/sed -n -e 's,^.*/CreationDate 
(D:\([0-9][0-9][0-9][0-9]\)\([0-9][0-9]\)\([0-9][0-9]\)\([0-9][0-9]\)\([0-9][0-9]\)\([0-9][0-9]\).*$,ctime:
 \1-\2-\3 \4:\5:\6,p' pressQA4.pdf 
ctime: 2000-01-28 18:01:48

Appended is the test file.
