Came up in cxx-discuss slack conversation. Here's the log:

If your code is running during static-duration shutdown (i.e. after main), it looks like there is a potential use-after-delete bug in introduced in SERVER-59463. https://github.com/mongodb/mongo/blame/fa7f62a123/src/mongo/logv2/log_detail.cpp#L50 That local static would be dead at some point after main exits, but while user code could still depend on it for logging.
(A StaticImmortal would fix it)
