[Sdcc-user] [BUG] sdcc fails to zero pad arrays properly

[Nick Craig-W. <nc...@ax...>]

SDCC doesn't initialise this properly.  Compile with 

  sdcc -mmcs51 --model-large --stack-after-data -c bug1.c

struct x {
    char a;
    char b[10];
};

struct x test[3] =
{
    { 1, { 1, 2, 3, 4, 5} },
    { 2, { 1 } },
    { 3, { 1, 2, 3} }
};

It doesn't fill the rest of the array with 0's so the structures don't
have the right length if you don't completely initialise the array.

__xinit__test:
        .db #0x01
        .db #0x01
        .db #0x02
        .db #0x03
        .db #0x04
        .db #0x05
        .db #0x02
        .db #0x01
        .db #0x03
        .db #0x01
        .db #0x02
        .db #0x03

Which is wrong because b has length 10.
