yeay... lifetime issues related to statics 🙄

[uklotzde]

Unlikely that this will ever get resolved.

[daschuer]

That is you opinion and no reason to close this bug, scheduled for 2.4.0.

[uklotzde]

No one other than me ever experienced this bug. I have opened this issue and I am free to close it whenever I decide to do so. Please respect my decision. Thank you.

@daschuer I agree with @uklotzde here, let's close this because we can't reproduce it. If we do, then we can reopen. I don't want to get into an open/close fight so please let me know if you agree.

From the backtrace is pretty clear what happens. The fix is here #12341
