Summary: When `module_spec.GetFileSpec().GetDirectory().AsCString()` returned a `nullptr` this line caused a segmentation fault: `std::string module_directory = module_spec.GetFileSpec().GetDirectory().AsCString()` Some context: I was remote debugging an executable built with Clang in an Ubuntu VM on my Windows machine using lldb-mi. I copied the executable and nothing else from the Ubuntu VM to the Windows machine. Then started lldb-server in the Ubuntu VM: ``` ./bin/lldb-server gdbserver *:8888 -- /home/enlight/Projects/dbgmits/build/Debug/data_tests_target ``` And ran `lldb-mi --interpreter` on Windows with the following commands: ``` -file-exec-and-symbols C:\Projects\data_tests_target -target-select remote 192.168.56.101:8888 -exec-continue ``` After which the segmentation fault occurred at the aforementioned line. Inside this method `module_spec.GetFileSpec()` returns an empty `FileSpec` (no dir, no filename), while `module_spec.GetSymbolFileSpec().GetFilename()` returns `"libc-2.19.so"`.
