Is not my responsability so I'll not insist.

But I just wanted to point out that I think this is clearly a bug in our
code, and it can trigger depending on decision of the tool-chain we have
no control over.

I think it should be trated as we would do if we discover and verify an
"access out of bounds" or "read after free".

My opinion :)
