Insufficient DWARF info with recent nightly

[Tiwalun]

That seems like an issue with rustc or defmt, both of which are not handled by this project. If debug info is missing, which seems to be the case based on the size of the binary, there is nothing we can do.

The Rust project is probably the place to ask for help.

Is the debug info on linux split on that nightly maybe? I cannot explain the drop otherwise.

I also thought it was split-debuginfo and tested it (and forgot to mention in the issue), but that's not it. However, I ended up figuring out what's going on. It's rust-lang/cargo#13257 meant to fix rust-lang/cargo#4122 which seems to only check whether debug is enabled at cargo level and not through RUSTFLAGS, so cargo was stripping debuginfo thinking the user didn't want debug. I'm fixing this in google/wasefire#499.

The current hint "compile your program with debug = 2" is technically correct when done in the Cargo.toml. It simply is not enough when using RUSTFLAGS, where -C debuginfo=2 -C strip=none is actually needed.

Thanks for the rubberducking!

Well the hint is debug = 2 not -C debuginfo=2 ;)

Yes that's why it's technically correct :-)

(Writing "enable debug" would not have been technically correct, it needs to be "enable debug in cargo".)
