Anyone help me with a stack dump?

[Cecil Ward]

The unitttests that I have just put in crash spectacularly with 
an access violation. I built the code with LDC for Aarch64 / OSX 
and I fired up lldb. I now have to learn lldb quick. (BTW Where 
can I get an x86 / linux build of lldb or similar ?)

This is the stack dump, and I could do with some help decoding 
parts of it
