// Make sure we can throw exceptions from work items executed via
// QueueUserWorkItem.
//
// Clang doesn't support exceptions on Windows yet, so for the time being we
// build this program in two parts: the code with exceptions is built with CL,
// the rest is built with Clang.  This represents the typical scenario when we
// build a large project using "clang-cl -fallback -fsanitize=address".
//
// RUN: cl -c %s -Fo%t.obj
// RUN: %clangxx_asan -o %t.exe %s %t.obj
// RUN: %run %t.exe 2>&1 | FileCheck %s
