Don't know if this is releated, but we exprience a similar issue (works on
GCC5, fails on 6 and 7).
Newest snapshot build gcc-7-20171005.tar.xz:
internal compiler error: in assign_temp, at function.c:968
mY(obs.mZ - ProjectState<Obs,
ProbabilityDensity>::project(prediction.getMean(), obs)) {
(the error arrow points at last ")"
I cannot include the preprocessed code.
It works with -O1 to -O3, but fails with -O0
