Re: [mesa-users] Segfaults when running from photo

Warrick,

The photo restarts aren't guaranteed to work across versions of MESA.
>From the "How to Use MESA" web page:

"Also, it should be emphasized that the photos are not intended for
long-term storage of models—the ‘save_model_number’ scheme described
above is meant for that purpose. Instead the photos are intended for use
during one specific run. In particular, when you update to a new version
of MESA star, you should expect your existing photo files to become
obsolete. If you have a lengthy run in progress when you want to update
MESA, then you should do ‘save_model_number’ to save state before
starting the update, and then do ‘load_saved_model’ to resume the
evolution after you have done the update."
