Description

Simulating the elliptical disk model xml file with the ctobssim tool results in a segmentation fault.

Ouput when running ctobssim in gdb:

Maybe you need to recompile your code?

I think, however, that the code should be modified so that the reading of the XML file is all done at the base class level.
