Yes I thought so as well, that was a quick fix for a friend in need.

You mean, having get_line() reallocate 1kB more each time it runs out
without finding a \n?
Btw, I noticed there was an avio_get_line() which was quite similar,
maybe those could be merged?

Right. Preallocating at least 1kB would fix it though.
