I am attempting to use a randomvar in a model, like so:
class evcharger_rand {
randomvar work_dist;
}
object evcharger_rand{
mileage_classification 73;
name evcharger_det_0;
parent evcharger_house_0;
work_dist ype:weibull(0.5,0.5); min:0.0; max:1.0; refresh:1h;\;
}
where evcharger_rand is some of my own custom code.
Running this model results in a segfault in random.c at Line 1301 when var->update_rate tries to deference var, whose address at this point is 0x4052400000000000.
Tracing the issue back, it seems as though var->next on Line 1336 should be yielding a NULL but isn't.
Therefore, I investigated randomvar_create() at Line 1259. And found that it was called only once and that var->next at that time was NULL.
Looking in convert_to_randomvar(), I found that var->next was 0x4052400000000000 when this function was called.
My conclusion is that var->next is getting altered sometime between the calls to randomvar_create() and convert_to_randomvar().,

(Note: my custom code is not making such a change to my knowledge. It simply tries to observe the value of the randomvar.),
