Invalid char pointer deference behavior

[ChAoSUnItY]

Considering the following code:

#include <stdlib.h>
#include <string.h>

char a[100];

typedef struct {
    char *raw;
} data_t;

void init_data(data_t *data, char *raw) {
    data->raw = raw;
}

int main() {
    strcpy(a, "DATA");
    data_t *data = malloc(sizeof(data_t));
    init_data(data, a);
    
    char *raw = data->raw;
    printf("%c\n", a[0]);
    printf("%c\n", raw[0]);
    printf("%c\n", data->raw[0]);
    
    
    free(data);

    return 0;
}

Using gcc to compile the program and run it, it would output:

D
D
D

But using shecc, it would output:

D
D

This happens because of the incorrect deference assembly code.
