Could you please clarify, what are the exact reproduction steps? Are they:

1. Have host aarch64-linux-android, stable Rust 1.90
2. Check out franklaranja/ratatui-garnish@087d800
3. RUSTFLAGS=-Cembed-bitcode=no cargo test

[franklaranja]

That is correct, I run rust within termux, which has its own tust packages
(not rustup). The bug happens when I run cargo test and the testing reaches
doc_tests.

To reproduce in termux:

• install rust packages (apt install ...)
• clone my repo
• run cargo test --features=serde,decorated_widget

Line 28 in bd3ac03

if id == self { index } else { outline(|| panic!("Unable to verify registry association")) }

panic is here, so this looks related to the thread setup.. that's quite weird
