Bug ID: 41368
Summary: clang++ accepts self-referring static member
initialization
Product: clang
Version: 8.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org

StackOverflow question (which started out differently):
https://stackoverflow.com/q/55505257/1593077
Consider the following code:
struct bar { static const bool value = !bar::value; };
This should not compile; and indeed, it doesn't - with GCC and with MSVC. Yet
clang++ is somehow willing to take a default-initialization value for
bar::value before it has actually been initialized. I am not a C++ language
lawyer, but I'm sure that's wrong.
