Hi
I've run across the following gcc "feature":
char c[4] = "01234";
gcc emits a nice warning
warning: initializer-string for array of chars is too long
But do a
char c[4] = "0123";
and - a wonder - no warning. No warning with gcc 3.3.2, 3.3.5, 3.4.5,
4.1.2. I was told 4.2.x does produce a warning. Now do a
struct {
char c[4];
int i;
} t;
t.i = 0x12345678;
strcpy(t.c, c);
and t.i is silently corrupted. Just wanted to ask if this is known,
really...
Thanks
Guennadi
