I can reproduce it here with Rev. 189737; it also crashes without running
valgrind.

It crashes (on x86-64 openSUSE Factory) with
  -O3 -ffast-math [-g]

It does not crash with either of the following added:
  -fno-fast-math
  -fno-inline-functions
  -fno-predictive-commoning
  -fno-tree-vectorize

  -fno-protect-parens  (implied by -Ofast)

Nor does it crash with:
  -O2 -ftree-vectorize -finline-functions -ffpredictive-commoning -ffast-math
  -m32 -O3 -ffast-math
