Yes, although it's purely theoretical:

Yes, have a look at the check directory.

No.

Valgrind reports the memory allocated for static objects as a leak. AFAIK
valgrind does so for any C++ library which has static objects (with
non-trivial constructors and destructors), so this might be a misfeature
of valgrind. Still I'm not quite sure, this might be also an actual bug.
Any ideas on debugging this are wellcome.

I routinely use GiNaC in long-running computations, so the *actual* memory
leaks get noticed and fixed (see e.g. commit 
dcb1d9061e4ce0a012d145530384541fc941fef4).

Best regards,
