// FIXME(dliew): Duplicated from `test/sanitizer_common/TestCases/Darwin/symbolizer-function-offset-dladdr.cpp`.
// This case can be dropped once sanitizer_common tests work on iOS devices (rdar://problem/47333049).
// NOTE: `detect_leaks=0` is necessary because with LSan enabled the dladdr
// symbolizer actually leaks memory because the call to
// `__sanitizer::DemangleCXXABI` leaks memory which LSan detects
// (rdar://problem/42868950).
// RUN: %clangxx_asan %s -O0 -o %t
// RUN: %env_asan_opts=detect_leaks=0,verbosity=2,external_symbolizer_path=,stack_trace_format='"function_name_%f___function_offset_%q"' %run %t > %t.output 2>&1
// RUN: FileCheck -input-file=%t.output %s
