Gilles updated MATH-995:

Attachment: gaussian__sigma_1000_zoom.png

gaussian__sigma_1.png
I attached plots that hint to why the "IterativeGaussLegendreIntegrator" is not
adapted to this particular change of variable.
It appears to be a limitation of the algorithm but not a bug in the
implementation.

> I think the existing Legendre-Gauss object fails for certain integrals. An
> example of failure and a solution that divides segments based on error is
> provided. Please let me know if I'm not using the Legendre-Gauss object
> correctly.
