Re: [avr-libc-dev] Stack pointer loaded on main entry?

Oops, I overlooked that one. From the avr-libc documentation,
chapter "Memory Sections":

.init2:
    In C programs, weakly bound to initialize the stack.

And indeed, gcrt1.S initializes the stack in .init2. But this is
completely senseless, because that stack setting is never used,
before main overrides it.
