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
