I'm trying to rebuild bind-9.9.4-12.P2.fc20.src.rpm with

I did the simplest possible thing - edited the original spec file (see
spec.diff) and built the package:
$ rpmbuild -ba bind.spec
The package builds and BIND itself seems to work. The problem is that new
debuginfo package is missing 118 out of
283 header files in /usr/src/debug/bind-9.9.4-P2.
It seems that "-O0" alone (instead of "-O0 -ggdb") causes the same problem.
I would be glad if anyone can give me advice how to debug this.
Original packages from Fedora 20 (with all headers in /usr/src/debug):
http://koji.fedoraproject.org/koji/buildinfo?buildID=502596
Packages built with -O0 -ggdb (scratch build):
http://koji.fedoraproject.org/koji/taskinfo?taskID=6778483
just don't do that
I'm going to reproduce and debug issue in named. Do you see any specific
reason why I should use -O2 for serious debugging/development sessions?

Thank you very much for your very helpful advice! :-)
the debuginfo package is your smallest problem
I'm afraid it is not.
you just kill security features like D_FORTIFY_SOURCE with -O0
warning: #warning _FORTIFY_SOURCE requires compiling with optimization (-O)
[-Wcpp]
I think my use case justifies it.
