Summary: Resizing of SymmetricMatrix fails for BOOST
Product: BFL
Version: trunk
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: wrappers

While extending the matrixwrapper test I noticed that the resizing of
SymmetricMatrix causes some troubles when using BOOST.
The test code I used is:
// SYMMETRICMATRIX
SymmetricMatrix Ks(r+2); Ks = v;
SymmetricMatrix Ks_resize(r); Ks_resize = v;
CPPUNIT_ASSERT_EQUAL(Ks.rows(), r+2);
CPPUNIT_ASSERT_EQUAL(Ks.columns(), r+2);
Ks.resize(r);
While executing the test for BOOST the following error is returned:
____________________________________________________________
Assertion failed in file /usr/include/boost/numeric/ublas/storage.hpp at line
182:
i < size_

It seems to me that this is a bug in boost or a mistake in using boost.
I posted a message on the Boost-users and Boost-ublas mailing list concerning
this problem.

a double.
