That's a bug in your compiler. We've had this discussion some months ago. Since we do not want to support broken compilers, we decided the ones with broken compilers should add initialization on their own, I think... Sorry.

Initializing globals to zero is defined in the C standard somewhere. If you're interested in where (e.g. want to tell your compiler vendor to fix it), you can search the mailing list archive for the discussion, it was mentioned here a while ago.
