Sorry but there is no later version of the compiler I see available. Since the issue is compiler related, not CCS, there is not much help I can provide.
You can try reposting your question but modify the wording so that you specify the issue you found with v4.4.1 of the compiler and that you are looking for a workaround, without any mention of CCS. I suspect the moderator saw your first post as "how to I upgrade the compiler version in CCS" and moved it here since you mentioned CCS and updates.
