// UNSUPPORTED: ios
// FIXME(dliew): We currently have to use module map for this test due to the atos
// symbolizer changing the module name from an absolute path to just the file name.
// rdar://problem/49784442
//
// Simulate partial symbolication (can happen with %L specifier) by printing
// out %L's fallback which will print the module name and offset instead of a
// source location.
// RUN: %clangxx_asan -O0 -g %s -o %t.executable
// RUN: %env_asan_opts=symbolize=1,print_module_map=1,stack_trace_format='"    #%%n %%p %%F %%M"' not %run %t.executable > %t.log 2>&1
// RUN: FileCheck -input-file=%t.log -check-prefix=CHECK-PS %s
// Now try to full symbolicate using the module map.
