Passing a const-reference to blaze::data() results in compiler error

[Mikhail Katliar]

Example:

#include <blaze/Math.h>

int main(int, char **)
{
    blaze::StaticMatrix<double, 3, 2> const m;
    data(m); // ERROR
    m.data(); // OK

    return 0;
}

I believe in this line https://bitbucket.org/blaze-lib/blaze/src/37136e84c08df0d0eaec9eb1eb2901c8b556fcf6/blaze/math/expressions/DenseMatrix.h#lines-213 it should be typename MT::ElementType const* instead of typename MT::ElementType*.

Hi Mikhail!

Thanks a lot for creating this bug report. You are correct, this is obviously an error in Blaze. We will fix the problem immediately.

Best regards,

Klaus!

Commit c305971 fixes the free data() for dense matrices. The fix is immediately available via cloning the Blaze repository and will be officially released in Blaze 3.6.
