I'm using below settings to build. CFLAGS="-march=native -O2 -pipe -fno-devirtualize" CXXFLAGS="${CFLAGS}" MAKEOPTS=-j1 FEATURES="-distcc -ccache"
Hi, I have multiple boxes here that show the same misbehavior as stated in this bug report. I made some tests, and now I know that this is caused by the gcc update from 4.8.4 to 4.9.3. When I switch back to 4.8.4, mythtv builds without errors.
This seems to be a duplicate of bug #516692. As stated there, I was able to compile mythtv with gcc-4.9.3 by switching my CFLAGS from -O2 to -O1.
I tried one more time and this time the build was successful. Not sure what has changed in this system. I'm marking it as solved.
