Looks like data corruption. Can't help you much without a full 
piece of code that *reproduces* the issue (reducing it helps too).

For what it's worth, your "weird" value, it appears to be a 
bitmask:
18446744073709551615
0x1999999999999999
0001_1001 1001_1001 1001_1001 1001_1001 1001_1001 1001_1001 
1001_1001 1001_1001

This is usually tell tale invalid memory reads and/or stack 
corruption.

TIP: Try marking your function @safe, if possible. It will limit 
the amount of unsafe things you can do, or at least, point you to 
the unsafe things that could be the source of the problem.
