Package: python-sparse
Version: 1.0.1-5+b1
Severity: grave
Justification: renders package unusable
I installed python-and often when I ran code involvind it, it causes
segmentation faults.
I hope this helps,
Thanks, Oz.
here's an example which causes that:
from numpy import *
from pysparse import *
m = 4
n = 3
nodec=0
A = spmatrix.ll_mat(m*n, m*n)
H = 3
V = 2
a = [0,0,0,] #row index
b = [0,1,n] #column index
val = [H+V, -H, -V] #node value
w=m*n
nodec=0
w=m*n
bottomr=w-n
for i in range(w):
for j in range(w):
if (nodec)<bottomr:#check necessary to make sure we
don't
#try puting south neighbours for the bottom row of nodes
b.append(nodec+n)
a.append(nodec-1)#row index, we skipped the
first node
val.append(-V)
nodec=nodec+1
A.put(val,a,b)
print A
for i in range(w):
for j in range(w):
if (nodec-n)>=0: #check necessary to make sure we don't
#try puting north neighbours for the top row of nodes
b.append(nodec-n)
a.append(nodec-1)#row index
val.append(-V)
nodec=nodec+1
A.put(val,a,b)
print A
Also a log of crash:
In [20]: a
Out[20]: [1, 3, 5]
In [21]: b
Out[21]: [2, 3, 5]
In [22]: c
Out[22]: [4, 5, 9]
In [23]: A.take(c,a,b)
Segmentation fault
