// GNU driver doesn't handle .so files properly.

// This test ensures that we call __asan_init early enough.
// We build a shared library w/o asan instrumentation
// and the binary with asan instrumentation.
// Both files include the same header (emulated by -DFUNC here)
// with C++ template magic which runs global initializer at library load time.
// The function get() is instrumented with asan, but called
// before the usual constructors are run.
// So, we must make sure that __asan_init is executed even earlier.
