This weekend I budgeted "a few hours" to learn about stack unwinding, but oh what a journey down the rabbit hole it became. This esoteric topic lies at the intersection of compilers, linkers, loaders, debuggers, ABIs, and language runtimes. There is precious little documentation about it and, from what I can tell, a small handful of guys who answer all the questions about it. People speculate about what happens if Linus Torvalds gets hit by a bus; I think we're just as screwed if the fellowship of linker/loader wizards bite it (or decide to change careers). But I digress.
