Is this also a problem with
  sparse(zeros(3))
and
  sparse([],[],[],3,3)

sparse needs to pass malloced pointers to dCreate_CompCol_Matrix.
If the matrix is all zeros, I have code to increase the size
of the allocated memory to 1 byte. However, this might break with
Solaris malloc.

Is anyone seeing this problem on other architectures?
