Two swap_endian() calls in e_datafile.c pass the size in bytes instead of in
number of units to be swapped, resulting in memory corruption and consequent
crashes.

The attached patch fixes this and allows teeworlds to work on my PowerBook.

Hi,

Thank you for the patch. Is the bug also present in Teeworlds 0.4.2?

Cheers,

I don't know if it's exactly the same in that version, but I was never
