Package: python-numpy
Version : 1:1.1.0-3+lenny1
When using "numpy.fromfile" on a corrupted file, numpy runs
into an infinite loop with memory lack.
$ dpkg -s libc6 | grep ^Version
Version: 2.7-18
$ uname -r
2.6.29-2-amd64
$ cat corrupted.txt

$ python
Python 2.5.2 (r252:60911, Jan 4 2009, 21:59:32)
[GCC 4.3.2] on linux2
>>> import numpy
>>> f = open('corrupted.txt')
>>> data = numpy.fromfile(f, dtype=float, count=-1, sep='\t')
The infinite loop can not be interrupted with "^C". One has to kill the
python process.
Note that in 'corrupted.txt' there is a '0,7' around line 10 while the
rest are only '0.0'.
This problem can not be reproduced on Version : 1:1.2.1-1.1

The bug is indeed no more present in the version of numpy in
testing/unstable. Even if I acknowledge the presence of this bug in
stable, there is no update pending (nor planned) for numpy in stable,
so I'm simply marking this bug as closed in the version you've
specified.
It you really need an updated version, you can try to get numpy from
testing, or alternatively, ask for a backport (for example dropping an
email to [email protected]) .
Reagrds,
