findpanics - Find calls to panic functions in rust executables

Use disassembly and DWARF debugging information to find calls to panic functions. Currently only tested on Linux.

This tool is intended for auditing specific aspects of an executable. You will never avoid most panics in rust code, but avoiding panics in specific locations may be possible.

Installing

After installing Rust, run:

cargo install --git https://github.com/philipc/findpanics

Running

Usage: findpanics <FILE>

The current directory must be the top level of a crate.

A whitelist of allowed panics is read from findpanics.yaml in the current directory. Currently this whitelist must be created manually.

Example output
