Package: grep
Version: 2.27-2
Severity: normal
There seems to be a problem with beginning/end-of-line anchors in regex
containing back-references:
$ cat words
ana
deed
ill
stats
Using -x to match whole line works:
$ egrep -x '(.?)(.?).?\2\1' words
ana
deed
stats
Using explicit anchors emits false positives:
$ egrep '^(.?)(.?).?\2\1$' words
ana
deed
ill <<<
stats
On the other hand, colouring the output shows that grep somewhat knows its
mistake:
$ egrep --color '^(.?)(.?).?\2\1$' words
ana (coloured)
deed (coloured)
ill
stats (coloured)
