The following code fails using -maix64 (g++, NOT gcc).  Using -DFIX64 (to make
the structure size a multiple of 8 bytes fixes the problem).

#include <stdio.h>
#include <string.h>

typedef struct _x {
    char str1[80];
    char str2[40];
    int i;
#ifdef FIX64
    int dummy;
#endif
} x;

int sub( x d )
{
    printf( "%s\n", d.str1 );
    printf( "%s\n", d.str2 );
}

main()
{
    x data;
    strncpy( data.str1, "this is the first test string", 80 );
    strncpy( data.str2, "this is the second test string", 40 );
    sub(data);
}
