Misaligned Read (mar) Error

Problem: Attempt to read data from an address without proper alignment.

Possible causes: Reading 2, 4, or 8 bytes from an address that is not half-word-aligned, word-aligned, or double-word-aligned, respectively.

Example:

char *s = “hello world”;
int *i = (int *)&s[1];
int j;

j = *i;                    /* Misaligned read (mar) */
