refCastFrom possible UB implementation

I'm quite unsure of this implementation:
https://gitlab.eclipse.org/eclipse/aidge/aidge_core/-/blob/main/include/aidge/data/Tensor.hpp?ref_type=heads#L640 AFAIUnderstand: device() call creates a std::pair rvalue on which your taking a const reference.
When passing a rvalue by const reference it extend its lifetime till the end of the function. In the current case I don't know the rule. Standard should be checked in order to be sure that device reference does not get dangling.

changed milestone to %v0.1.0

added Bug 🐛 Discussion labels

added LanguageC++ label

The answer is in your issue: "When passing a rvalue by const reference it extend its lifetime till the end of the function". This is not limited to function arguements.
