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