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