Seg. Fault in do_sort_ascending
When running swift, I get a segmentation fault in runner.c:255. I suppose it is due to the variable pivot being set to -NaN.
My IC is a Gadget simulation of a dwarf galaxy where I removed the stars and the DM (Thus a simulation of gas only).
I run swift with the following command and you can find my IC and output on https://obswww.unige.ch/~lhausamm/swift/issues/sort/
swift -s -t 1 params
