The content of the baz function has always been on line 5, not line 15. Presumably it previously accidentally worked as the call in the foo function is on line 15, but now it likely tail calls to bar.

// Test that when debug info only includes line tables that backtrace is still generated

// successfully.

// Original test:

// <https://github.com/rust-lang/backtrace-rs/tree/6fa4b85b9962c3e1be8c2e5cc605cd078134152b/crates/line-tables-only>.
|
|
// Part of <https://github.com/rust-lang/rust/issues/122899> porting some backtrace tests to rustc.
|

// This test diverges from the original test in that it now uses a Rust library auxiliary because

|
// rustc now has `-Cdebuginfo=line-tables-only`.
