I get a segfault from this line of code:
int fatblob[1820][286][5];
Why is that?

You’re trying to allocate
1820 * 285 * 5 * sizeof(int)bytes = about 10MB (ifsizeof(int) == 4). That’s probably more bytes than your OS gives you for stack allocation by default, so you get a stack overflow/segfault.You can fix this by either asking for extra stack when you create the thread, allocating on the heap, or changing the OS defaults.
