            Bug ID: 26481
           Summary: CUDA __global__ lambdas shouldn't be allowed to
                    capture by reference
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: justin.lebar at gmail.com
                CC: dgregor at apple.com, llvm-bugs at lists.llvm.org
    Classification: Unclassified

The following CUDA code should be an error, as __global__ lambdas aren't
allowed to capture variables by reference.

void foo() {
  int v;
  auto x = [&v] () __global__ { };
}

Today it's a different error:

test.cu:3:17: error: kernel function type '<dependent type> () const' must have
void return type
  auto x = [&v] () __global__ { };

We get this error with or without a capture-by-reference, but that's a separate
issue.
