C++ Composer XE 2013 Update 5 (2013.5.198) Bug?

[Pavel_Holoborodko__A]

Hello,

Here is the code which compiles fine with MSVC 2010, ICC 11, 12, 13 but 13.1 with latest update 5 chokes on it:

#include <Eigen/SparseQR>

using namespace Eigen;

int main() {
  typedef Eigen::SparseMatrix< double > SparseDoubleMatrix;

  SparseQR< SparseDoubleMatrix, COLAMDOrdering<int> > solver;

  SparseDoubleMatrix A(10,10);   // Just dummy matrix for now (I know how to use SparseMatrices properly :)) 
  solver.compute(A);
}

See this thread for more information: http://forum.kde.org/viewtopic.php?f=74&t=112254&p=289884

My system is Windows 7 64-bit, Intel C++ integrated into MSVC2010.

Overall last update seems to have some imperfections. The most painful among other issues - multi-processor compilation (/MP) doesn't work anymore (before update 5 it worked just fine on the same project).

How I can roll back to previous update?

Thank you,

Pavel.

Did you verify SparseQR why class Eigen::BlockImpl does not have any longer the C++ operator =? >>...How I can roll back to previous update? Download it from Intel Software Registration Center, uninstall the current one and install the previous again.

@ Did you verify SparseQR why class Eigen::BlockImpl does not have any longer the C++ operator =?

Of course, class Eigen::BlockImpl has "operator=" implemented. Other compilers have no problem with compiling the same code - MSVC2010, gcc and even ICC for Linux.

The only compiler complaing about non-existent "operator=" (which is in fact implemented) - ICC for Windows.

This is very unfortunate since Eigen is one of the most used C++ libraries for matrix cdomputrations (code comes from it).

Any ideas when this case will be investigated and bug fix issued (if any)?

Thank you,

Pavel.
