Description
So I found this while trying to solve a tarpaulin issue on a project where I'm not familiar with the code at all. The project is https://github.com/winksaville/rust-binance-auto-sell Using cargo 1.53.0-nightly (65d57e6f3 2021-04-04) my steps were:
cargo build
`RUSTFLAGS=" -C link-dead-code -C debuginfo=2` cargo build
Tarpaulin changes the rustflags to add RUSTFLAGS=" -C link-dead-code -C debuginfo=2 hence the minimal instructions. This also doesn't happen in stable, instead I get this issue (rust-lang/cargo#9220). Also both stable and nightly work if started from a clean build
I'll try and look into the code to figure out a minimal reproducible example but like I said I'm not familiar at all with it at all. I'll also let a maintainer know about this and maybe they'll have a better idea.
Error output
I get a list of types that fills up my terminal I've attached it here:
