This is a Docker image that contains the multi-arch-gdb tool. It's useful in cases where installing the conda environment is more challenging than running a Docker container.

Example usage to analyze a core file:

# this repo has an example core + symbol file under the "example" directory
❯ docker run --rm -t -i --volume "$PWD":/data memfault/multi-arch-gdb \
    gdb --se example/symbol_file.elf --core example/coredump.elf
