Most of the other backtaces are identical (Conservation Test has an extra frame, but Springboard is very different). I have a "workaround" to avoid the faults, which seems to indicate the issue is lists of constraints are not being added when a soft body is added but despite not crashing they still seem wrong.
I've tried building from a few different commits in the past but none appear to work. I also tried it on a beefier Windows machine and it's also crashing there.
