The regression test cases were extracted from Apple's libunwind-35.1, where they
are used to validate Apple's compact frame and dwarf unwinding implementation.

A custom build script (build-regression-tests.sh) may be used to regenerate
the test binaries.

The test cases themselves are licensed under libunwind's license:
