I just submitted a re-build of ODB for GCC 4.9.2 in rawhide ( http://koji.fedoraproject.org/koji/taskinfo?taskID=8051892 ) and it ran into an issue ( http://koji.fedoraproject.org/koji/taskinfo?taskID=8051895 ).
I don't have access to a machine with rawhide to do any more debugging, but I've included the pertinent output below and what's the recommend path for working on getting this resolved?
Perhaps http://gcc.gnu.org/PR60871 , but without a preprocessed testcase it is hard to tell. You could either try local mock, or you could hack for a temporary build small *.spec file change that would BuildRequire: sharutils and run: make ... || tar cjf - /tmp/cc*.out | uuencode cc.tar.bz2 (that way you could download build.log and uudecode the tarball with the preprocessed source from it).
As a workaround, supposedly -fno-devirtualize or -fno-devirtualize-speculatively options could help.
