--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Lemetter Sebastien from comment #2) > With this compiler version: > ❯ /usr/bin/g++-9 --version > g++-9 (Ubuntu 9.4.0-1ubuntu1~20.04.2) 9.4.0 > > the bug does not occur. The problem is that our target is to compile for QNX > on ARM architecture, and the cross compiler we got is: > > ❯ q++ -V > cc: targets available in /opt/qnx710/host/linux/x86_64/etc/qcc: > 8.3.0,gcc_ntox86_64_cxx > 8.3.0,gcc_ntoaarch64le_gpp > 8.3.0,gcc_ntoarmv7le > 8.3.0,gcc_ntoarmv7le_gpp > 8.3.0,gcc_ntox86_64 > > So I could use GCC v9, but it will not help me with my target build. Could > you just confirm if this bug was ever reported? We are working in the > automotive industry, and there, you don t update easily your compiler. It > must be certified, which takes years. We have even issues with using > compiler flags. That s why we are only using -o2 and not -o3 Note in such cases the vendor providing the compiler should provide support to you.
