New issue 22 by charlesm...@gmail.com: Crashes on Lion
http://code.google.com/p/freetype-py/issues/detail?id=22

What steps will reproduce the problem?
1. Build and install Freetype 2.4.9
./configure --host=i386-apple-darwin
sudo make install

2. Install freetype-py 0.3.3
sudo python setup.py install

3. Run trivial python program:
from freetype import *
library = FT_Library()
error = FT_Init_FreeType( byref(library) )
FT_Done_FreeType(library)

What is the expected output? What do you see instead?
Expected behavior: python script runs without crashing.
Observed behavior: python script runs crashes on exit every time.

What version of the product are you using? On what operating system?

Mac OS X vesion 10.7.3

It turns out that if you just use freetype.Face(...), this crash doesn't
happen. I don't need other functionality, so this resolves my issue, but
you may still want to pursue this.

Thanks for the report.
Your script does not seem to crash on my machine so it's rather hard to
debug.

Anyone got the same crash ?

Comment #6 on issue 22 by gulug...@gmail.com: Crashes on Lion
http://code.google.com/p/freetype-py/issues/detail?id=22

Nevermind. A bit of digging and realized that this is just a wrapper which
does not list the dependency of what it is wrapping. Installing the actual
FreeType library fixes my issue, and probably would solve a few other
reports I've seen.
