           Summary: clang crashes in DefineImplicitMoveAssignment since
                    r138821
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++0x
        AssignedTo: unassignedclangbugs at nondot.org

on Windows 7, given crash.cpp:

struct A {
  unsigned var[1];
} ;

A foo(A);

void crash()
{
  A tmp;
  tmp = foo(tmp);
}

clang -std=c++0x crash.cpp

changing 
  unsigned var[1];
to 
  unsigned var;
fixes the crash.

This problem is currently blocking my testing of clang on MFC code.
