The usual error that happens with expression templates is that you return a
reference to a temporary object, using it after its lifetime ended. What
you then can observe is that if you inline enough the error goes away.
But this is just a wild guess. Instead you need to track this down further
to a smaller testcase (without the complete expression template machinery).
Oh, and the testcase crashes with -O2 for me; with gcc 4.0, 4.1, 4.2 and trunk.
It doesn't build with 3.4, so I didn't verify there. It already crashes with
void matrixOps()
{
EiMatrix<int, 2, 3> a, b;
a = a + b;
}
my bet would be a bug in your code.
