IIUC, -Wvla-larger-than=NNN weakens the check done by -Wvla such that it only complains about a subset of vlas that are unbounded or larger than the noted size. Given that we had this typo, we were only ever using -Wvla. Since we compile without warnings, we evidentally don't have any vlas that trigger with -Wvla at all. So by that rationale I think -Wvla-larger-than=NNN is redundant and can be removed entirely Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
