[mesa-users] seg faults

I am evolving a star with an initial mass of 2 solar masses with a central lower limit species stopping condition.
I have inconsistently received seg faults, once around the 300th model, and another time around the 640th model.
For reference, please find below my inlist_project, and the final outputs of the seg faults.
To note, the ‘reduce dt because of …’ changes from ‘varcontrol’ to ‘dH_div_H’ around the 420th model.
Sincerely,
Jacqueline
