Hello,
I'd like to report a weird crash issue from V8 v13.5 to v13.7.
- Compile and run the following code in V8, then get an instance of
v8::internal::JSFunction.
(() => {
let a = 1;
let b = 3;
return () => a + b + 1;
})();
- Get v8::internal::SharedFunctionInfo from
v8::internal::JSFunction::shared().
- Get v8::internal::ScopeInfo from v8::internal:: SharedFunctionInfo
::scope_info(v8::kAcquireLoad).
- Call v8::internal::ScopeInfo::scope_type() and V8 crashes.
It seems v8::internal::ScopeInfo is not fully initialized and the memory is
corrupted in this case. Most of the API crash as well. E.g. IsEmpty(),
Flags(), etc. If I run that function, the memory corruption will be fixed
and there will be no more crashes.
My test env is: Windows 10 64bit + Visual Studio 2022 v17.13.6 + V8
v13.5-v13.7.
Best regards,
Sam
