If you call Stream::hasNewFrame(), can m_newFrame be undefined?

So if you call Stream::hasNewFrame() before you've captured any frames, what's the value of m_newFrame?

I ran into a 'illegal instruction' when I build this with zig cc, so I guessed what was happening was it was getting caught by one of clang's sanitizers: whatever value m_newFrame is, it shouldn't actually matter, so it runs just fine when you turn off all the sanitizers.

PS: I had a look at it in gdb, and m_newFrame looks like garbage to me: it's got a value of 152 right now, which seems funny for a bool.
