Bug ID: 112712 Summary: Crash when compiling g++ -m68020-60 -O2 Product: gcc Version: 13.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: miro.kropacek at gmail dot com Target Milestone: --- Created attachment 56688 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=56688&action=edit Preprocessed output This is a crash which seems to be specific to the -m68020-60 option (or better said to 060 code generation as the only other option where this bugs occurs is -m68060). When changing to any other CPU (-m68000, -mcpu=5475, ...) and/or changing to -O1, -O0, ... everything is fine.
