Hello there,
I am running with V8 3.31, the debug version, and I get this crash upon
allocating a large string:

My code appears in the next frame, and says something like:
v8::Local<v8::String> vSource = v8::String::NewFromUtf8(isolate, src,
v8::String::kNormalString, len);
As you can see, the string is quite large (431185 bytes long). Any idea why
this is happening? What can I do about this?
Regards,
Danny
