Package: grep
Version: 2.5.1.ds1-4
Severity: normal
I was under the impression that I had reported this bug long ago, and
that it had been fixed after some time, but I haven't been able to find
it in the BTS, so I guess I was wrong.
Using back references as in the expression:
'^(.?)(.?)(.?)(.?).\4\3\2\1$', causes grep to misbehave.
Some examples (I'm using LANG=C to prevent any locale problems):
***
$ LANG=C egrep '^(.?)(.?)(.?)(.?).\4\3\2\1$' /usr/share/dict/spanish
a
grep: regexec.c:1244: pop_fail_stack: Assertion `num >= 0' failed.
Abortado
$ LANG=C egrep '^(.)(.?)(.?)(.?).\4\3\2\1$' /usr/share/dict/spanish
grep: regexec.c:1244: pop_fail_stack: Assertion `num >= 0' failed.
Abortado
***
These two don't work, and they give a reference to where the problem
might be located. Now, taking one more question mark out, makes it
work:
***
$ time LANG=C egrep '^(.)(.)(.?)(.?).\4\3\2\1$' /usr/share/dict/spanish
adamada
afufa
anilina
anona
arenera
nomon
ososo
radar
rajar
rapar
rasar
rayar
razar
recocer
reconocer
rever
rodador
rotor
yatay
real 0m3.990s
user 0m3.412s
sys 0m0.013s
***
It takes a lot of time, when doing a normal grep that does not use back
references on the same file:
***
$ time LANG=C egrep '^rec.*cer$' /usr/share/dict/spanish
recocer
reconocer
reconvalecer
recrecer
recrudecer
real 0m0.015s
user 0m0.007s
sys 0m0.006s
***
Takes almost no time.
I _think_ this bug was not present in woody. I'm pretty sure that I
successfully executed the back-references regexp some years ago,
although I don't remember when it was that it broke.
Please, do have a look at it.
Love,
Margarita Manterola
