It is more complicated.

I recommend to read and understand the whole process before starting it --
the instructions should probably be adjusted to your configuration.

Here are two patches for LazFreeType.

- minimum size of 1 point, to avoid error with underlying procedures
- interpreter of true type program moved into one class (so it can be multithreaded) and dynamic stack size (this solves many fonts that use more stack than they declare)

EDIT : note that for multithreading to be ok, it is needed that an execution context be created for each thread

>>Here is a patch for file access :
I recently created a bug report about it http://bugs.freepascal.org/view.php?id=23888

The patch changes not only ttinterpreter, but also ttobjs. Make sure you applied it to ttobjs.

Has all these patches been applied - there seems to be no confirmation on any of them? Why don't you guys use Mantis where patches can be more easily tracked. Or use Git or something so patches can be even easier tested by others.
