Crate stack_trace_frame_pointers

Stack trace (backtrace) functionality using frame pointers.

There are two main ways of obtaining stack traces:

1. Using the frame pointer register to find the previous stack frame.
2. Using DWARF debugging information to understand the layout of each stack frame.

We support both ways, but prefer #2 because it doesn’t suffer from the compatibility and performance drawbacks of #1. See the stack_trace crate for the #2 functionality.

This crate offers support for #1. The advantage of using this is that it doesn’t require any significant dependencies. However, this crate’s frame pointer-based stack traces are only available when the compiler has been configured to emit frame pointers, which in Rust is achieved via the -C force-frame-pointers=yes rust flags option.
