Error due to empty field

[LeoneChen]

In get_stack_frame, it assumes that the subfields in stack_frame_index_ all have valid values, for example file_location.function_name_id() must have a non-zero value, and then it will be used in this line:

xla/xla/hlo/ir/hlo_module.cc

Line 112 in d863e4e

stack_frame_index_->function_names(file_location.function_name_id() - 1);

But when I have such a xla::HloModuleProto, corresponde json likes this file test.json . Pay special attention to this field fileLocations, the second item of function_name_id is empty, so the result in the above code line is '0 - 1'.

"fileLocations": [
            {
                "fileNameId": 1,
                "functionNameId": 1,
                "line": 67
            },
            {
                "fileNameId": 1,
                "line": 59
            }
        ],
