V8 8.1 disabled unboxed double fieds, which means all double fields are now stored on memory as references to HeapNumber objects instead of the double value. In theory V8 could store boxed doubles before, but we didn't take it into account in our dobule fields code. In the future, V8 intends to re-enable unboxed doubles, which means we'll need to add logic to handle both types of fields in the same llnode session. This also fixes a bug where llnode was not handling double fields at all in some cases. Fixes: nodejs#353 Signed-off-by: Matheus Marchini <[email protected]>

I'm getting the OS X failures on master as well, and we're also seeing it on the daily runs: https://github.com/nodejs/llnode/runs/603630513?check_suite_focus=true. I think something changed on OS X lldb output when running a program, because that's where the test is failing. Will open an issue to investigate. In the meantime, llnode should still work on OS X, but we don't have coverage until the issue is resolved. |

didn't take it into account in our dobule fields code. In the future, V8
intends to re-enable unboxed doubles, which means we'll need to add
logic to handle both types of fields in the same llnode session.
