Hello
The Completion/Base/Utility/_store_cache function is missing the local declaration for _cache_dir. Thus it is global. I do not see any reason for it to be global seeing that it's value is coming from zstyle in the function body.
Because _cache_dir is global, it is overwriting my named ~directory for the compsys compcache directory.
I believe line 5 should be changed to:
local _cache_ident _cache_ident_dir _cache_dir
Thanks
Jacob
