I was aiming that comment more at the other people with problems
(non-windows).

There should be numbered points (i.e. something is going wrong).

That was what was strange.  When I run through gdb it works, outside gdb
it doesn't...

This is still the same (similar) problem.  The 4 fonts used are
cube-outline, cube-fill, point-outline, point-fill.  It seems like some
of these randomly fail.

Note that using msdev to build, I get no problems at all.

I think there is just a random memory type problem in the freetype
library.  The FTGL code is quite straight forward and I can't see
anything that could be going wrong.  On the other hand the freetype
library is anything but straight forward...
