testcase

I have a testcase which contains a single #pragma GCC visibility pop at the
end, and this causes an ICE in llvm-g++ that doesn't occur in my copy of GCC
4.2.

$ g++-4.2 421.c -O2
421.c:2: error: expected type-specifier before ‘ptrdiff_t’
421.c:2: error: expected ‘>’ before ‘ptrdiff_t’
421.c:7: error: expected unqualified-id before ‘}’ token
421.c:10: error: expected `}' at end of input
421.c:10: error: expected `}' at end of input
$ llvm-g++ 421.c -O2
421.c:2: error: expected type-specifier before ‘ptrdiff_t’
421.c:2: error: expected ‘>’ before ‘ptrdiff_t’
421.c:7: error: expected unqualified-id before ‘}’ token
421.c:10: error: expected `}' at end of input
421.c:10: internal compiler error: vector VEC(visibility,base) pop domain
error, in pop_visibility at c-pragma.c:637
