build error C4716: 'v8::ArrayBuffer::Allocator::Reserve': must return a value

[langxiong]

• Version: node-v8.1.0
• Platform: Windows-10
• Subsystem: x64

Build node.js from source, with command:

.\vcbuild.bat debug x64 vs2015

got a error:

c:\users\x5831\node\node-v8.1.0\deps\v8\src\api.cc(440): error C4716: 'v8::ArrayBuffer::Allocator::Reserve': must retur
n a value [C:\Users\x5831\node\node-v8.1.0\deps\v8\src\v8_base_1.vcxproj]

And I check the source code, 'api.cc'.

void* v8::ArrayBuffer::Allocator::Reserve(size_t length) { UNIMPLEMENTED(); }

Solved this by add a return nullptr;

void* v8::ArrayBuffer::Allocator::Reserve(size_t length) { UNIMPLEMENTED();  return nullptr;}

@langxiong thank for the report. AFAIK C4716 is a warning. Do you have anywhere a directive to treat warnings as errors?
