This is not "major" severity because the code is invalid, so it's just error
handling.

> BUG1:
> auto sz = []()->constexpr long { return 100L; };
This is invalid, constexpr is not part of the return type, it's a function
specifier. G++ correctly rejects it. The "bailing out" is due to the next
line:
> int arr[[]()->long { return 100L; }];
This is also invalid, but shouldn't cause an ICE, and 4.7 doesn't get an ICE
here:
l.cc:2:38: error: size of array 'arr' has non-integral type '<lambda()>'
4.6.1 segfaults here:
Program received signal SIGSEGV, Segmentation fault.
