Backtrace does not include file and line number on non-Linux platforms #24346
Description
When a Rust program run with RUST_BACKTRACE=1 panics it outputs backtrace which only has function names (with noisy hashes), but doesn't include file names and line numbers.
RUST_BACKTRACE=1 cargo run --verbose --example test
12: 0x1088db5d9 - main::hed092b4e13c9cca7Iaa
During development (not necessarily in release builds), I'd prefer something like:
12: 0x1088db5d9 - main() at test.rs:10
Sometimes line numbers are very important, e.g. if the panic is some generic out-of-bounds assertion, and the function uses vectors and slices in many places, just the name is not enough to pinpoint the offending expression.
