Today I noticed that the weird b + + c; expression is considered valid in C. I am wondering if there is a reason behind it; especially, given that b ++ c; and b + ; are considered syntax errors. I do not know where to look for some information, I thought Stack Overflow might be a good place to ask for some insight. (I am using gcc for compilation)

If I conditionally initialize a const reference to refer to either a global object or a temporary returned from a function, the compiler calls the destructor when it goes out of scope in both cases, so the global object is destroyed twice.
