            Bug ID: 17214
           Summary: inline stepping test fails on FreeBSD
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: FreeBSD
            Status: NEW

TestInlineStepping.test_with_dwarf_and_python_api fails
test code is test/functionalities/inline-stepping/calling.cpp

Reproducing manually, after 'log enable -f /dev/stdout lldb step'
