Crash in V8 when working with big arrays

[danilaml]

Since upgrading from Node.js 8.2.1 I often get

#
# Fatal error in ../deps/v8/src/runtime/runtime-internal.cc, line 349
# Check failed: size <= kMaxRegularHeapObjectSize || space == LO_SPACE.
#

when working with large arrays.

From some investigation it looks like I've hit
https://bugs.chromium.org/p/v8/issues/detail?id=6716
which was recently fixed (not sure if it's in 6.1 or 6.2 branch).

I've tried with latest (8.5.0) Node.js and the issue is still there.

• Version: 8.5.0
• Platform: 4.4.0-83-generic #106-Ubuntu SMP Mon Jun 26 17:54:43 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
• Subsystem: V8?

Code examples are in the V8 issue linked above and here.

From the issue it sounds like the fix made it into V8 6.1. So, if #15393 lands, we don’t have to worry about this, if not, we’d probably need to float a patch?

/cc @nodejs/v8

V8 6.1 has landed and the fix is included there so this is fixed. @fhinkel Can you close please :D
