Use of tracing in Drop will cause SIGABRT in thread-local context #231
Description
I'm writting an egui app. And from some point of time my app stop terminating gracefully. And I git few panics instead.
A quick investigation led me to the idea that the order of Drop is not controlled in any way, and thread-local tracing was dropped first, so by the time the tracing method was called with nothing.
panic thread 'main' panicked at 'Thread count overflowed the configured max count. Thread index = 18446744073709551615, max threads = 4096.': /home/sc/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/sharded-slab-0.1.7/src/shard.rs:295 0: ss_common::setup::panic_log::panic_hook
