t.C:21: error: could not convert template argument MatrixBase::M to unsigned

the template also declares the methods M() and N(), when M, N are also template
parameters. (The code snippet is obviously buggy.)

Also, if I remove the derivation from the MatrixBase abstract base class, the
error disappears.

I can reproduce only with 4_2-branch (no longer maintained) and 4_3-branch. I
can't with 4_4-branch and mainline.

Isolate to the method:
Matrix::Matrix & operator*=( double f ) ...
The template takes 2 args, but the above makes g++ crash. If I take out one
parameter (e.g., Matrix), then I get a compiler error as expected.
