[Bug c++/34298] New: [3.4] ICE on templated class with statically sized array computed from static const member

I'm not really sure how to explain this one, so I'll let the attached reduced
test case do the talking. The same code compiles fine on the same machine
running g++-4.1.2-20061115 (Debian prerelease 4.1.1-21)

Output of `g++ -v`:

Reduced test case

The two branches of the '#if' should be functionally identical, but the one
indicated as doing so in the comments crashes the compiler. Reported error is:

test.cxx: In instantiation of `void set<Item>::clear() [with Item = int]':
test.cxx:3:   instantiated from `set<Item>::set() [with Item = int]'
test.cxx:19:   instantiated from here
test.cxx:4: internal compiler error: Segmentation fault

Yes, and active branches are all fine.
