[Bug c/19435] New: spurious warnings with nested array constructors

[rfeany at mrv dot com]

I have tried this with both gcc 3.3.5 and 3.4.4:

gcc-3.4 (GCC) 3.4.4 20041218 (prerelease) (Debian 3.4.3-6)

Here is code:

struct thing {
    unsigned char *ptr;
};

struct thing array[1] = {
    { .ptr = ((unsigned char []) { 0x1, 0x2 }) }
};

And the warnings I don't think I should be getting:

{rfeany@bugs}$ gcc-3.4 -c test.c 
test.c:9: warning: excess elements in array initializer
test.c:9: warning: (near initialization for `(anonymous)')


If i change array[1] to array[2] then I recieve no warnings.
It seems as if the outside array size is being used to check the internal
array constructor thinggy.
