This seems to only happen when self-compiling rust 1.51 with rust 1.51; building 1.51 works with rust-1.50
That happens from time to time, I’ll check for patches or will limit version to previous. As alternative - install previous rust-bin or disable sysyem-bootstrap.
this will help https://github.com/rust-lang/rust/commit/31c93397bde772764cda3058e16f9cef61895090#diff-6e3c7e8b58a9a198adc885bced48fff2c5fd9a1ee126ccce52166476a536807f it does not change the compiler itself, just makes the bootsrtapper build with new rust. will add it soon.
