Because every project hosted at GitHub deserves a good Markdown formatted README.

Hi, sorry for the late reply.

First of all thanks for the effort. However, currently this is only a fork of the original project with a few patches. That's why I'm keeping the original README. Later on when I have time to revise and improve the project further, I'll have a prettier README. ;)

The root cause is a off by one error in coord_to_cell(), so the

bb->prev was only partially initialized.
prev.id was initialized to ID_DAMAGED, but prev.overflow can be set
to true. bbulk_draw() relied on the fact that the last cell of each
row can't have overflow=true.
But because memory is unitialized it might still be the case, and it can cause a
memory overflow as it uses offset + 1.

Fix both, by clearing the memory before using it, and also
checking that prev->overflow is valid only if it's not the last cell
of the row.
