After a couple of days silence, the mysterious entity in my computer is bac= k. This time it is again a weird compiler message of failure (trying to buildworld): [...] c++ -O2 -pipe -O3 -O3 -I/usr/src/lib/clang/libllvmsupport/../../../contrib= /llvm/include -I/usr/src/lib/clang/libllvmsupport/../../../contrib/llvm/tools/clang/inclu= de -I/usr/src/lib/clang/libllvmsupport/../../../contrib/llvm/lib/Support -I. -I/usr/src/lib/clang/libllvmsupport/../../../contrib/llvm/../../lib/clang/i= nclude -DLLVM_ON_UNIX -DLLVM_ON_FREEBSD -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MA= CROS -fno-strict-aliasing -DLLVM_DEFAULT_TARGET_TRIPLE=3D\"x86_64-unknown-freebs= d11.0\" -DLLVM_HOST_TRIPLE=3D\"x86_64-unknown-freebsd11.0\" -DDEFAULT_SYSROOT=3D\"\" -Qunused-arguments -I/usr/obj/usr/src/tmp/legacy/usr/include -std=3Dc++11 -= fno-exceptions -fno-rtti -Wno-c++11-extensions -c /usr/src/lib/clang/libllvmsupport/../../../contrib/llvm/lib/Support/Host= .cpp -o Host.o --- GraphWriter.o --- In file included from /usr/src/lib/clang/libllvmsupport/../../../contrib/llvm/lib/Support/Gr= aphWriter.cpp:14: /usr/src/lib/clang/libllvmsupport/../../../contrib/llvm/i= nclude/llvm/Support/GraphWriter.h:269:10: error: use of undeclared identifier 'DOD'; did you mean 'DOT'?

I can not reproduce them after a reboot, but as long as the system is runni= ng with this error occured, it is sticky. So in order to compile the OS successfully, I = reboot. Does anyone have an idea what this could be? Since it affects at the moment= only one machine (the other CoreDuo has been retired in the meanwhile), it feels a b= it like a miscompilation on a certain type of CPU.
