[Bug 44405] Rise Of Nations Extended edition, Steam version crashes with page fault when trying to list mods

--- Comment #10 from Richard Yao  ---
To make it more clear, the problem is that encodeBase64W is trying to
dereference invalid memory. It looks like it is being done on this line:

/* first char is the first 6 bits of the first byte*/
*ptr++ = b64[ ( d[0] >> 2) & 0x3f ];
