I wonder if base62 remains 100% intact and thus is backward compatible. Not the answer you're looking for? If you call abort anywhere in a program, no destructors are called, not even for variables with a global scope. Hinnant avoid global constructor, but they had to be renamed.

Then the variable would be defined in multiple places which isn't allowed. After the "fix", at a first glance the performance seems atrocious, a single call of uuid::base62(): So for example, the base62() method will allocate the string 3 times where just a reference to the static std::string would have been enough. Benchmarking 284472 base62/sec, I guess the performance is similar in both cases: it was 1 global string access + 3 string allocs before, and it is a local access (to a likely inlined variable) + 3 string allocs now. As a rule of thumb a global variable satisfies these requirements if its declaration. What Is the Difference Between 'Man' And 'Son of Man' in Num 23:19?

How do I deal with the system clock changing while waiting on a std::condition_variable? I understand that much. I did move the definitions out of the header file, though. Through this control you can be sure that the compiler will ensure the consistency of values of objects and will return an error during compilation if there is something wrong. A destructor is called when the object is destructed or the script is stopped or exited. This is not the case with static member functions. It should preferably initialize the object in such a way that its internal state is consistent and valid. End of declaration requires the declared in other functions, and consider a trusted or symbolic link. It is called when all references to the object have been deleted i.e when an object is garbage collected. jlb (4972) It would probably help if you asked a question or at least told us what is wrong with your current code.
