Do dispersive materials break load_flux_data on an eigenmode monitor?

[Andeloth]

I'm running simulations with

• dispersive materials
• the load_minus_flux_data trick for the reflection monitor.
• an eigenmode monitor.

I was able to successfully record the flux data for reflection correction, but when I call load_minus_flux_data to load the fields, the kernel crashes which is usually due to a runtime error in the C++ code. I have been able to use eigenmode monitors with dispersive materials without using load_minus_flux_data which is why I was hoping it would work.

Would using load_minus_flux_data with dispersive materials and mode monitors break meep with the current implementation, or should I be looking for an answer somewhere else in my code?
