I think that zero initialization is a consequence of how the process images is created. For example: static char a[65536]; will make the .bss section of size ~65536 bytes which is allocated by the dynamic linker by means of mmap() which always provides zeroed-out pages. So to answer your question: global variables are likely to be always initialized with zero (it's out of gcc-s hands). Stack variables, on the other hand, are "initialized" with whatever is on the stack, which yeah, if you don't explicitly initialize them, could be called uninitialized. :) -- Mihai DonÈu (unices@xxxxxxxxxxxxxxx)
