    PR tree-optimization/50328
    * tree-vect-loop.c (vect_is_simple_reduction_1): Allow one
    constant or default-def operand.

    * gcc.dg/vect/fast-math-vect-outer-7.c: New testcase.

Note that the ICE is replaced with a segmentation fault for compilers
bootstrapped with --enable-checking=release.
