No. I compiled the version before that (9042ece787cf93665776ffb69893fcb1357aacbe) and it crashed with exactly the same crash. So, no, it must have been introduced before that.
On the other hand, I have been working before this with a version from Dec 1, 2019 (I think 9f2145f42daab13aed5cf89fdb6a7c5579819ec0) and I have used that quite a time without crashes. Whereas the other versions crashed 1-2 times a day.
