Looks like it has always been a bug in GCC (tried GCC 4.4.7 and up) and was only fixed in GCC 12.1.0. I have not looked into which patch fixed this though but you could do a "git bisect" to find the patch or ask a few people who have pre-built binaries to find the patch which fixed it. I doubt we are going to backport the fix to a GCC 11 release either since it is NOT a regression from an earlier version. Thanks, Andrew Pinski > > Thanks and regards > Shivam
