Crash on hyperjump #5909

Closed impaktor closed 3 months ago

impaktor commented 3 months ago

Observed behaviour

Crash when hyperjumping. Initially I though it was due to me making an illegal jump, or from a partially compiled master. I've removed build/ directory and re-compiled. Still crashes.

Steps to reproduce

My pioneer version (and OS): f59dfb09c

I recently did a system update, so got new version of gcc (14.2.1), and friends

Turns out I had starfield density = 0 (not sure how that happened). I deem this to be a duplicate of #5880, as @zonkmachine pointed out in IRC
