There is almost nothing there. It builds, and then on i386 we get a run-time
error and it shows is

Trivial code: swZ.selfadjointView<Lower>().rankUpdate(swZ):
from
http://win-builder.r-project.org/u84hzB80Fol0/examples_and_tests/minimalTest-Ex_i386.Rout
and the summary in http://win-builder.r-project.org/u84hzB80Fol0/00check.log
Can you expand on it? Decompose the expressesion? Compare it to alternate
versions of the same expression?
I don't know how to decompose it further in more elementary steps. I can
surely compute a cross-product in a different way.
However, having submitted 131 versions of packages to win-builder in the
last week in order to produce the small example, and given how slow
using win-builder makes any debugging attempt, I wish someone would be
able to reproduce the problem on another machine, or else to give me
more specific advice as to what alternative versions of the code would
be most useful to test, because I feel have reached the point where my
limited understanding of Eigen and RcppEigen's internals makes the blind
testing exercise too inefficient.
