Bug ID: 84152 Summary: Internal compiler error when compiling a cxx file Product: gcc Version: 7.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: drohr at jwdt dot org Target Milestone: --- Created attachment 43308 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43308&action=edit preprocessed source file to trigger the segfault gcc encounters an internal compiler error when compiling our software. I have preprocessed the affected source file and attached to this bug report. The command line to trigger the problem is: c++ -O3 -march=native -c ~/tmp/gcccrash.cxx -o ~/tmp/gcccrash.cxx.o I am running gentoo linux 64 bit, gcc 7.3.0, glibc 2.26, kernel 2.15. CPU model is Intel(R) Core(TM) i7-6700K. The problem appears only when the -O3 and the -march=native options are present.
