[eigen] matrix-size-mismatch error in EIGEN_TEST_PART1 test/triangular.cpp

[Manoj Rajagopalan <rmanoj@xxxxxxxxx>]

Hi eigen developers,

   I am trying to build the test suite off the default branch in the Hg repo. The following line in test/triangular.cpp is causing a 
matrix-size-mismatch static assertion fail on my platform:

void test_triangular() { // ...
    CALL_SUBTEST_1( triangular_square(Matrix<float, 1, 1>()) );


Commenting this line out gets the compilation back on track. Looks like the corner case of a 1x1 matrix needs a little more 
attention.

My platform is gcc 4.2.4 / KUbuntu 8.04 / Intel Core 2

The exact error log is provided below. My working copy is in sync with the Hg repo and I have made no changes. 

thanks,
Manoj
