struct shortwrap{short s; inline shortwrap(short q){s=q;}};

struct pkf{
 long a;
 float b;
 shortwrap c[4];
 double d;
};

#include <stdio.h>
int main(){
 pkf t={0x33333333,0.1f,{4,{6,},8,9,},1./7};
 for(int i=0;i<sizeof t;i++){printf("%02x ",((unsigned char*)&t)[i]);}
}

Here a structure is being initialized. The expected bytes are the following:
33 33 33 33 cd cc cc 3d 04 00 06 00 08 00 09 00 92 24 49 92 24 49 c2 3f

However, the items initialized by short initializing shortwrap array overwrite the start of pkf structure instead of the proper position.
04 00 33 33 08 00 09 00 00 00 06 00 00 00 00 00 92 24 49 92 24 49 c2 3f

Notice that the 6, which is initialized directly from the shortwrap structure entries is initialized in the correct location, but 4, 8, and 9 end up corrupting structure start.
