--- Comment #2 from James Greenhalgh <jgreenhalgh at gcc dot gnu.org> ---
Should reproduce further back if you force it on with -ftree-vectorize .
i.e.
gcc foo.c -ftree-vectorize -O3
Breaks somewhere between:
gcc version 7.0.0 20160615
gcc version 7.0.0 20160907

tree-optimization/95133 - avoid abnormal edges in path splitting
When path splitting tries to detect a CFG diamond make sure it
is composed of normal (non-EH, not abnormal) edges. Otherwise
CFG manipulation later may fail.
