--- Comment #3 from 慕冬亮 <mudongliangabcd at gmail dot com> --- At first, I reported it in bugzilla of binutils(https://sourceware.org/bugzilla/show_bug.cgi?id=23008). The developer said it should be the issue of C++ demangle code and GCC maintains this component. He advised me to post this bug in GCC Bugzilla.
