stacktracer

This program crawls its own stack frames and dumps information about it.

As the code that performs the stack tracing is not written in a way that allows it to be used by other programs, there isn't much practical utility to it.

Here are some known limitations:

• This program probably only works on x86_64 linux machines (it may work on the *BSDs).
• It is not able to resolve functions that live in dynamically linked libraries (for example, libc)
• The names are mangled
