ran xpu-smi on dGPU environemnt, met segement fault. centos7.4 met this issue, ubuntu20.04 works well.

void attribute((destructor)) driverHandleDestructor() {
std::string loaderLibraryName= "lib" + L0::loaderLibraryFilename + ".so.1";
L0::setDriverTeardownHandleInLoader(loaderLibraryName);
L0::globalDriverTeardown();
}
after triage, found variable L0::loaderLibraryFilename is released during driverHandleDestructor, so segment fault happen. it works, when using std::string loaderLibraryName = "libze_loader.so.1";
maybe registering atexit callback is better.
