Hey there, I'm facing a bug regarding outer array sizes if it is initialized at
the definition. Details below. If more information is required feel free to
ask.

impulze at istari ~/clang $ gcc -ansi -pedantic -Wall -Wextra -o a.out main.c &&
./a.out
28080
0x601220 0x607fd0 28080
tests: teststring array1 teststring array2
tests:  teststring array2
impulze at istari ~/clang $ cat main.c 
#include <stdio.h>
#include <string.h>

char array1[351][80] =
{
    "teststring array1"
};

char array2[][20] =
{
    "teststring array2",
};

int main()
{
    printf("%ld\n", sizeof(array1));
    printf("%p %p %ld\n", (void *)array1, (void *)array2, (char *)array2 -
(char *)array1);
    printf("tests: %s %s\n", array1[0], array2[0]);
    memset(array1[0], 0, sizeof array1);
    printf("tests: %s %s\n", array1[0], array2[0]);

    return 0;
}
