Elegant is terminated witn an error "Terminated by SIGSEGVProgram trace-back:" if you try to use the ILMATRIX in tracking (but it's OK to use it in Twiss parameters calculation).
Please see the attached example for details.

Re: ILMATRIX bug
Alexey,
Sorry I didn't see this earlier. This is a known bug that I haven't gotten around to fixing.
The problem is that elegant is looking for twiss parameters, but they haven't been computed. You can fix this by adding
&twiss_output matched=1 &end
in the file after &run_setup.
See attached.

Re: ILMATRIX bug
Thanks Michael!
For my simulation linear_chromatic_tracking_setup turned out to be just fine, so this bug was not critical to me.
Of course ILMATRIX is more flexible, so I'll be using this element instead of linear_chromatic_tracking from now on.
