I'm glad you found the solution.

Yes, to minimize time spent parsing files, CEDET will keep pre-parsed 
file data around.  A side effect is that when you change parsing data 
(like the preprocessor table) you need to manually flush your cache.

It is more about the aggressive data caching that causes the issue.  I 
don't think it matters where the data is stored.

If you set semanticdb-default-save-directory to nil, it will save cache 
files next to the files that it is caching instead of in .semanticdb.

There isn't much you can do as far as configuring where the databases 
are stored other than the above, nor even what they do unless you opt to 
start coding up new ones, in which case there isn't much doc for that 
either, just examples.

The file backed semantic databases are just one variant of a tag 
database.  There are also databases backed up by GNU Global cache files, 
EBrowse cache files, CScope cache files  (Not finished yet) or even one 
that is custom to the Emacs environment.  Creating new specialized 
databases is a good way to improve performance.
