I think that's a good idea. And that is why I'd like to leave the bug
open, not because of the buggy compiler.

Note that many pieces of embedded software that are supposed to be
ultra-portable provide compile switches whether to initialize the data
or not. I'll try to search for some C definition if the initialization
to zero is mandatory or not.
