// RUN: %clangxx_asan -std=c++11 -pthread %s -o %t && %run %t 2>&1
// Regression test for the versioned pthread_create interceptor on linux/i386.
// pthread_attr_init is not intercepted and binds to the new abi
// pthread_create is intercepted; dlsym always returns the oldest version.
// This results in a crash inside pthread_create in libc.
