{{char name[0];}} - ok... this is may be corrent, but
{{char *value;}} - its POINER but you use it not for pointer!

i think my patch is clear to apply....

or you must do some one like this - 

{code}
struct A{
char * name;
char * value;
char data[0];
}

A = calloc(1, sizeof(A) + strlen(some_name)+1 + strlen(some_val)+1);

memncpy(A.data, &some_name, strlen(some_name));
a.name = &A.data; // pointer to data buffer

memncpy(A.data + strlen(some_name) +1, &some_val,strlen(some_val));
a.value = A.data + strlen(some_name)+1; // pointer to data buffer


{code}
