Reproduces only on aarch64 in release mode (tried on r6g.xlarge)

To reproduce:

1. ./dragonfly --timeout=500
2. redis-cli DEBUG STACKTRACE

crashes in absl code inside absl::lts_20240722::GetStackTrace().
Something is special in ConnectionsWatcherFb that reproduces it.
One direction is - to just remove pieces of code there until we understand why it happens.
Another option is to check if newer version of absl (say https://github.com/abseil/abseil-cpp/releases/tag/20250512.1) fixes the issue.
