Posting about this on HN has brought to my attention
the fact that I should've use alloca instead of using malloc / free.
This is a fair point so I figure I may as well fix it.

FWIW Writing snide little remarks on twitter doesn't make you an all
knowing superiour being. It makes you an unhelpful, egotistical asshole.
How about trying to be helpful instead?

- I have comments enabled on my blog.
- I have a public github repository hosting the code.

Why not use them in a constructive manner rather than shitting
all over somebody to make yourself feel more important?
