javascript - V8: Fatal error: CHECK(V8::ArrayBufferAllocator() != NULL) failed -

i error when try run js code (this + this) v8 (tried master 2 weaks ago, 3.23.17, 3.24.40, 3.25.5; 3.23.0 doesn't work anymore because of api changes):

# # fatal error in ..\..\src\runtime.cc, line 785 # check(v8::arraybufferallocator() != null) failed # 

a lot of other js code has worked already, wonder problem is.

it's on win8 x64 build. v8 has been build described in official docs (using gyp + msvc 2012). don't think there problem because worked fine other js code.

i think there might issue v8 itself, not sure...

i asked on mailing-list here.

some c++ code, don't think there problem because worked fine other js code:

you need initialize array buffer allocator.

use malloc, example:

class mallocarraybufferallocator : public v8::arraybuffer::allocator { public:   virtual void* allocate(size_t length) { return malloc(length); }   virtual void* allocateuninitialized(size_t length) { return malloc(length); }   virtual void free(void* data, size_t length) { free(data); } }; 

initialize:

v8::v8::setarraybufferallocator(new mallocarraybufferallocator);
