Bug#680931: libarmadillo-dev: trivial program fails to compile

[Jet Holloway]

Package: libarmadillo-dev
Version: 1:3.2.3+dfsg-1
Severity: grave
Tags: upstream
Justification: renders package unusable

Dear Maintainer,

I just upgraded libarmadillo-dev and libarmadillo3 from version 3.2.2+dfsg-1
to 3.2.3+dfsg-1, which caused a program I was working on to fail to compile.
When I removed 3.2.3 and reinstalled 3.2.2 the problem disappeared.


The following trivial program also causes the error:
#include <armadillo>
int main()
{
    return 0;
}


When I try to compile this program with "g++ armadillo_bug.cpp", I get these
errors:

In file included from /usr/include/armadillo:141:0,
from armadillo_bug.cpp:2:
/usr/include/armadillo_bits/Mat_bones.hpp:545:26: error: no members matching ‘arma::Mat<eT>::operator=’ in ‘class arma::Mat<eT>’
/usr/include/armadillo_bits/Mat_bones.hpp:546:27: error: no members matching ‘arma::Mat<eT>::operator()’ in ‘class arma::Mat<eT>’

from armadillo_bug.cpp:2:
/usr/include/armadillo_bits/Row_bones.hpp:173:27: error: no members matching ‘arma::Row<eT>::operator()’ in ‘class arma::Row<eT>’


I am using gcc 4.7.1-2.
I have also downloaded armadillo-3.2.3.tar.gz from the armadillo website and
tried including that header file in the trivial program. This also failed to
compile.
