Setting a breakpoint in gfc_simplify_len, it appears that the substring length
is not properly set:

Duh, we don't defer parsing of noexcept for any ptr-operator, like
struct S {
int& f() noexcept(noexcept(i));
int i;
};
Awkward, but the fix should be simple.

As I mentioned on IRC, it seems like this may just be a matter of properly
passing down flags/member_p in the recursive call to cp_parser_declarator.

Thank you - I'm aware GCC might optimize it out (and failed to test with
GCC10), at least in O2 mode, but other compilers might not, hence the code.
