Sorry, my above example is not good, it compiles and works ok;
What's really not working is this example by union:
union mbox {
int w[3];
short s[6];
char c[12];
};
If I declare a union mbox and want to initialize w[0], s[2] and c[6],
union mbox mbox = { .w = { 1, }, .s[2] = 2, .c[6] = 's' };
I want a mbox initialized with these 12 bytes (on little endian):
0000: 01 00 00 00 02 00 73 00 00 00 00 00
And actually I got these:
0000: 00 00 00 00 00 00 73 00 00 00 00 00
the hexdump result shows only last .c[6] make effect,
Wonder if this is a bug or not supported? Thanks,
