Incorrect hashes on small strings

[josefnpat]

I was double checking my indexes, and found a collision. Surpised, I did some more research:

nothanks@DESKTOP-616042V ~/repos/roguecraft-squadron
$ cat test1.txt
"Computer, what happened to the IEE Bishop?"

nothanks@DESKTOP-616042V ~/repos/roguecraft-squadron
$ cat test1.txt  | md5sum.exe

$ cat test2.txt
"Computer, what is Miho Takeda's current status?"

$ cat test.lua
md5 = require"src.libs.md5"

print(md5.tohex('"Computer, what happened to the IEE Bishop?"'))
print(md5.tohex('"Computer, what is Miho Takeda\'s current status?"'))

$ lua test.lua

22436f6d70757465722c207768617420

It seems that I not only found a collision, but also that hashes for smaller strings are not correct.

Am I doing something wrong, or is this a bug?
