I have the following code, which works fine on v8 7.2:
isolate::isolate() {
create_params.array_buffer_allocator =
v8::
ArrayBuffer::Allocator::NewDefaultAllocator();
i = v8::Isolate::New
(create_params);
i->SetData(0, this);
}
However, when run on 7.3+ it yields this:

I am building on Linux using clang 8, with the following parameters:
v8_build_args = [
'target_cpu="x64"',
'is_component_build = false',
'v8_enable_i18n_support = false',
'v8_enable_backtrace = true',
'v8_enable_disassembler = true',
'v8_enable_object_print = true',
'v8_enable_verify_heap = true',
'v8_use_snapshot = true',
'v8_use_external_startup_data = false',
'v8_monolithic = true',
]
Any help would be much appreciated.
