Code review comment for ~utkarsh/ubuntu/+source/isc-dhcp:fix-nm-regression

Hi Christian, Michael,

Good news, this issue is fixed when I use -O2 over -O3. I've updated the MP.
PPA at https://launchpad.net/~utkarsh/+archive/ubuntu/dummy

The bug has also been filed upstream; cf: https://gitlab.isc.org/isc-projects/dhcp/-/issues/170.
I'll keep a tab on this and will incorporate once the fix is available in Debian and sync then over.
