When I see a self-initialized variable, I think "bug", not "here there be dragons". Make your assumptions explicit with a comment please.

Additionally, if you *don't* initialize the variable then the compiler will be able to warn you if you later create a code path where you forgot...

Okay, user-space code, but when I set coding standards at a company, the rule was "all warnings must be explained away".

The reason was precisely that - we had certain code (where we called a commercial library that then called-back our code) that we just couldn't suppress all warnings.

Sometimes you end up between a rock and a hard place, and things like "var = var" are an easy escape route...
