// Multi-frame DWARF fixture for the #29f Phase-7 gate. A 3-deep call chain ending in a raw
// out-of-bounds load (a clean wasm `MemoryOutOfBounds` trap, no Rust panic machinery). Rebuild:
// cd src/module/debug/testdata
// rustc --target wasm32-unknown-unknown -C debuginfo=2 -C opt-level=1 -C panic=abort \
// --crate-type cdylib --remap-path-prefix "$(pwd)=." -o trap_chain.wasm trap_chain.rs
// wasm-tools strip -d producers -d target_features -d .debug_ranges \
// trap_chain.wasm -o trap_chain.wasm
// Each function is on its own line so the three backtrace frames map to distinct source lines.
