kimaprIm basically trying to debug an issue in btop where under heavy system load it can sometimes just hang (the stress test i’m using is filling up RAM with garbage until the whole system gets severe levels of thrashing). It’s pretty annoying to reproduce and often instead of hanging it crashes instead (or maybe commit 6164470 always crashes while 1.4.6 hangs. can’t really tell for sure nope 1.4.6 also crashes). For the crashes, the backtraces seem to always be like this:
