I find no description for "triplet", so guessing at its use, and see no method
of attaching .ii so attempting to fit all info in this form.

Problem seems to be from reinterpret_cast between vectors and unions of vectors
with arrays of scalars.
Occurred in machine-generated code, have not been able to substantially
simplify.

Error persists with -march=pentium4 -msse2 switches so is independent of
whether
vectors are generated or just simulated as array.

Identical error message occurs in gcc built from 4.1.1 sources on a PowerPC G4.

Error does not occur if I change to C-style casts and change extension to .c.

Unfortunately, semantics of C++ casting seem to change the C-style cast in
error.cpp to a static_cast, which then encounters a semantic error:
error2.cpp:144: error: no matching function for call to ‘__v4F::__v4F(float
__vector__&)’
error2.cpp:17: note: candidates are: __v4F::__v4F()
error2.cpp:17: note:                 __v4F::__v4F(const __v4F&)
Thus the attempt to generate a reinterpret_cast leading to discovery of bug.

 gcc -v
