[Bug 57628] Simple StackWalk64 code example doesn't produce output as expected

--- Comment #6 from Eric Pouech  ---
investigated a bit more the case of missing SymInitialize call

I can't even let Wine stack walk tests on Windows pass: it turns out that (in
this case) native calls the FunctionTableAccess64 function, which fails because
process is not initialized
the net result is that we can't unwind to the calling frame

and on amd64, calling into FunctionTableAccess64 is absolutely required for
proper unwinding

does your app pass FunctionTableAccess64 to StackWalk or is it a simplification
from your snippnet?

but with providing a decent implementation of these two functions for
StackWalk64, I can pass the test on native, and builtin as well

so there's nothing to "fix" here
