I used mock to compile the rust source package and it failed, saying "the compiler unexpectedly panicked. this is a bug"

This is a mock compiled log error

This is more detailed information about the statements in the errant spec file that were executed after entering the chroot compilation environment

info: using vendored source, but .cargo/config is already present.
Reusing the current configuration file. But you may want to configure vendoring like this:
[source.crates-io]
replace-with = 'vendored-sources'
registry = 'https://example.com'

[source.vendored-sources]
directory = '/builddir/build/BUILD/rustc-1.58.1-src/vendor'

There is no point posting this here. You should file a bug report on Github, the link is in your error message. Remember to provide a fully reproducing code example. Ideally you should minimize it, but if you don't, someone will do it later.
