Multiple callback calls in C++ Native Module crashes app
Problem Description
When you call a method, async or not, from a C++ native module which contains multiple invokes to the provided callback, the app crashes. A small example of a method:
REACT_METHOD(Add, L"add");
void Add(std::function<void(double)> callback) noexcept
{
callback(69.);
callback(69.);
}
I will provide a full example below so you can try it yourself easier.
Steps To Reproduce
- create a default RNW app like this
- create a simple C++ native module like this
- call the method from react native
Expected Results
In the example from the steps I provided I expected 2 console logs not a crash :))
