--- Comment #1 from Manuel Lauss <manuel.lauss at googlemail dot com> --- Created attachment 55767 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55767&action=edit another compressed unreduced testcase Another testcase. it triggers with "-march=zvner1" but not e.g. "core2" but that is probably due to the source being preprocessed for znver4. # g++ -march=znver1 -mtune=znver1 -O2 -c qxmlstream.ii during RTL pass: expand In file included from /tmp-ram/portage/dev-qt/qtcore-5.15.10-r1/work/qtbase-everywhere-src-5.15.10/src/corelib/serialization/qxmlstream.cpp:76: /tmp-ram/portage/dev-qt/qtcore-5.15.10-r1/work/qtbase-everywhere-src-5.15.10/src/corelib/serialization/qxmlstream_p.h: In member function 'QStringView QXmlStreamReaderPrivate::symView(int) const': /tmp-ram/portage/dev-qt/qtcore-5.15.10-r1/work/qtbase-everywhere-src-5.15.10/src/corelib/serialization/qxmlstream_p.h:949:17: internal compiler error: in expand_fn_using_insn, at internal-fn.cc:214 949 | QStringView symView(int index) const | ^~~~~~~ 0x555774d492af internal_error(char const*, ...) ???:0 0x5557732b9ed6 fancy_abort(char const*, int, char const*)
