Sam James <sam at gentoo dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sam at gentoo dot org --- Comment #24 from Sam James <sam at gentoo dot org> --- Please be polite on these bugs. There's a lot of documentation online about how to use UBsan. It's not ideal to upload a tarball with all of the bits, but if it's what's needed, then I guess so be it. Some build systems make it easier to enable sanitizers like Meson. GCC's bug tracker isn't for general support on how to use build systems and flags. The bug tracker is public and I don't think one can delete their own attachments. Are you saying that when you use -fsanitize=undefined and run your program, it gets SIGILL'd?
