Hello All,
Our project recently upgraded from v8 version 7.6 to 8.3. While running the
unit tests a couple of our tests fail with the following message only on
Windows and UBSan builds. The linux and MacOS tend to work fine.

I'm not really sure how to make sense of it. Seems like it has something to
do with the platform.
void initV8(const char* executable_img)
{
V8::InitializeICUDefaultLocation(executable_img, nullptr);
v8platform = platform::NewDefaultPlatform();
V8::InitializePlatform(v8platform.get());
V8::Initialize();
}
void deinitV8()
{
V8::Dispose();
V8::ShutdownPlatform();
}
This is how the code looks like!
Thanks
