stream tracer, save data, crashes
We have a crash when trying to save data from a stream tracer. Here is how to replicate.
- Master (Mid June, 2019), Linux, remote server (16 ranks).
- Load g1s1. All vars on. Apply.
- Stream tracer. Vectors: Vel. Seed Type: Point Source. Apply.
- Move forward one timestep. If desired, hide the sphere.
- File/ Save Data. Exodus. Don't save all timesteps.
Seg Fault. Lots of crash output verbiage gets written out, here is what I think is important (on the server side):

Important for Watney.
Marking as 5.7, but OK to slip to 5.8. Needs to not slip past 5.8.
