anyone have any thoughts as to why accessing the result of mmap as a CPointer<ByteVar> would cause a SIGBUS?

[Kris Wong]

val bytes = ByteArray(Int.SIZE_BYTES)
        bytes.setIntAt(0, newPos)
        bytes.forEachIndexed { i: Int, byte: Byte ->
            buffer[i] = byte
        }

[Kris Wong]

buffer = COpaquePointer reinterpreted as CPointer<ByteVar>

i wonder if it's because I am executing a test on the iOS sim, but using a file path with /tmp

but the call to mmap succeeds

[Kris Wong]

damn, have to explicitly ensure the file is the right size!
