Bug ID: 18260
Summary: Attempting to call member func named 'move' crashes
the compiler if using -Weverything
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org

test case to reproduce crash
If I have a class/struct with a member named 'move()' and a function that
attempts to call it (doesn't matter if it's through a pointer or reference),
then the code will build and run fine unless I attempt to build with
"-Weverything" - then the compiler crashes.
$ clang++ --version

$ cat ./move.cc
struct A
{
void move() {}
};
int main()
{
A a;
a.move();
}
$ clang++ ./move.cc
$ echo $?
0
$ clang++ -Weverything ./move.cc
