Looks like the bottom/top parameters to glOrtho are switched?

glOrtho(frustumSize*aspect, -frustumSize*aspect, frustumSize, -frustumSize, 1.0, 1000);

Should be:

glOrtho(frustumSize*aspect, -frustumSize*aspect, -frustumSize, frustumSize, 1.0, 1000);

Docs are here: https://www.opengl.org/sdk/docs/man2/xhtml/glOrtho.xml

    This is an old issue, and we don't use glOrtho any more. I don't think this bug is present any more.
