Look at the value of SEHandlerCount field of the IMAGE_LOAD_CONFIG_DIRECTORY of the instrumented file. If the value is zero, then your executable doesn't have safe exception handlers.

There is a bug in pe_file_parser.cc, PEFileParser::ParseLoadConfigDir. Before using load_config->SEHandlerTable, the code must check load_config->SEHandlerCount field. If it is zero, there are no safe SEH handlers and the attempt to read them (image_file_.Translate and seh_handlers.Read) must be skipped.
