There is no official guideline that I know, but considering other
problems like binary compatibility, switching to a CVS version can
always create trouble. Personally I would not suggest doing that for
an industrial project, except maybe if the deadline is more than 9
month ahead (i.e. you are reasonnably sure that a new release will be
available by that time).
On the upside, you can profit immediately from bug fixes, and
avoid preemptively bugs that would break your code in an upcoming
release. From this point of view, if you're a very active user, maybe
having the CVS version around for testing can be useful.

Concerning whether there are more or less bugs in the CVS versions,
like for all projects I would say this goes in cycles.
Typically, just after a release people do not immediately introduce
new features, and many bug reports come in, so that for a while the
number of bugs is actually going down.  Then you may get a big change
and it suddenly goes up, then down again thanks to benevolent CVS
testers.
Since there is no strict rule about when to commit (except code
freezes just before releases), it is very hard to tell what is the
current situation.
My personnal feeling that the CVS version of a few days ago is
more stable than 3.06, but then I don't test all parts of the
compiler.

Last thing, for people who might be tempted to use the CVS version:
please do not release code requiring the CVS version to run.  Forcing
it on other people may break their own programs.  But this is just
classical advice I believe.

Cheers,
