(In reply to comment #5)
There are (many!) changes of type:
- D.6241 = __builtin_sqrt (receive_coil_1.self_ind * transmit_coil.self_ind);
- coil_coil_mutuals[0] = coil_coil_mutuals[0] / D.6241;
+ coil_coil_mutuals[0] = coil_coil_mutuals[0] / __builtin_sqrt (receive_coil_1
where (-) represents failed run and (+) successful run, produced with Jakub's
patch removed.
