I have ported freetype to a processor as part of a small test project and spent
most of yesterday trying to find a crash in the system.
Went to bed with the problems and thought, check if Freetype is using volatile.
The reason for this is that the embedded chip i am working on has a cache
problem when using volatiles and these need to be handled in a certain way.
I did a grep and found volatiles used in numerous places, can someone please
explain why they are being used, as i understand and have used in the past
..... years freetype should not need volatiles, there are no interrupt calls
and no way in which data should be changed without a call into the freetype
engine?
