Describe the bug
When opening some RAW images I get a hard crash in my application when opening them with raw:Demosaic = "none". Specifically the debugger says:

HEAP[prog.exe]: Heap block at 000002166E310F50 modified at 000002166E312908 past requested size of 19a8

Crash stack for reference:

To Reproduce
Steps to reproduce the behavior:

1. Download image from evidence
2. Open image
3. Crash

Expected behavior
No crash please. Would expect it to throw an exception we can handle.

Evidence
Here is a direct link to the images which should be able to reproduce the crash. Just in case I'll also zip it and attach them here.
