I'm trying that experiment, but not getting very far.  The gcc used by fedora27 is already version 7.3.1, which is about as new as it gets.  So I don't think I can update gcc any further.

For clang, I get an early build error:

clang-5.0: error: unknown argument: '-fabi-version=11'

The full compiler command looks like this - note that clang++ is being used, but there are also several gcc-specific flags present:

usr/bin/clang++  -DCOMPILE_SGLIB -DHAVE_STDINT_H -DPCBNEW -DWXUSINGDLL -DWX_COMPATIBILITY -D_FILE_OFFSET_BITS=64 -D__WXGTK__ -Dkicad_3dsg_EXPORTS -I/builddir/build/BUILD/kicad-r11969.7ad436c7/include -I/builddir/build/BUILD/kicad-r11969.7ad436c7/3d-viewer/. -isystem /usr/lib64/wx/include/gtk2-unicode-3.0-gtk2 -isystem /usr/include/wx-3.0-gtk2 -I/builddir/build/BUILD/kicad-r11969.7ad436c7/3d-viewer -I/builddir/build/BUILD/kicad-r11969.7ad436c7/3d-viewer/../pcbnew -I/builddir/build/BUILD/kicad-r11969.7ad436c7/3d-viewer/../polygon -I/builddir/build/BUILD/kicad-r11969.7ad436c7/3d-viewer/3d_canvas -I/builddir/build/BUILD/kicad-r11969.7ad436c7/3d-viewer/3d_cache -I/builddir/build/BUILD/kicad-r11969.7ad436c7/3d-viewer/3d_rendering -I/builddir/build/BUILD/kicad-r11969.7ad436c7/3d-viewer/3d_viewer -I/builddir/build/BUILD/kicad-r11969.7ad436c7 -I/builddir/build/BUILD/kicad-r11969.7ad436c7/include/gal/opengl  -Wall -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic -Wno-unused-local-typedefs -Wno-strict-aliasing -pthread -fabi-version=11 -g3 -ggdb3 -DDEBUG -Wno-deprecated-declarations -fPIC -fvisibility=hidden -fvisibility-inlines-hidden   -std=gnu++11 -o CMakeFiles/kicad_3dsg.dir/sg_base.cpp.o -c /builddir/build/BUILD/kicad-r11969.7ad436c7/3d-viewer/3d_cache/sg/sg_base.cpp

So while I've gotten the build to use clang, it seems there are several gcc-only flags that are still being used.

Are there any flags that I need to pass to either cmake or to gnu make to fix this?  Seems like just overriding CC=clang and CXX=clang++ is insufficient to switch compilers.

But as of yesterday, when I tried rebuilding 7ad436c7 (from Dec 4 2017), I started seeing the errors that I reported.  I suspect it has more to do with a recent update to Fedora27, perhaps in gcc or a library, that has suddenly exposed the issue, rather than a specific commit to kicad.
