@safe:

```
source/AI.d(83,23): Error: cannot take address of local `rData` 
in `@safe` function `main`
source/analysisEngine.d(560,20): Error: cannot take address of 
local `rd_flattened` in `@safe` function `add_missingPoints`
source/analysisEngine.d(344,5): Error: can only catch class 
objects derived from `Exception` in `@safe` code, not 
`core.exception.RangeError`
```

And then, about half complaints about @system dlib calls and
complaints about `void*` <-> `rawData[]*` casting

The RangeError catch likely does nothing with your compile flags.

Even if you don't intend to use @safe in the end, I'd bet that the
segfaults are due to what it's complaining about.
