Arch Linux

Description: Hello, please provide the source code for the rust standard library in the package, so that it's possible to debug programs. Currently, it's not possible to debug any code because stepping in gdb results on it trying to step somewhere in stdlib code.


Additional info:
* package version(s)
rust 1:1.63.0-1

* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:
Example debugging session:
$ rust-gdb target/debug/tictactoe
