This "CCacheUsed" is messed up and it is likely to be the cause of
your memory allocation error. We check the amount of memory available
to the system and also the amount of available memory in the
compressed cache before returning allocation error. I am going to
check it.

BTW, I am going to file this bug report on the project site now. Con
Kolivas reported a bug that is likely to be related to the bug you
hit.

Thanks for the report.
