The testcase from #2 with gfortran 4.6 shows

No opt:

 cmplx_test (inf+iNan)*(2/3+i0)  (                      NaN,                   
  NaN)
 cmplx_test  (inf+iNan)*(2/3) (                      NaN,                     
NaN)


-O3:

 cmplx_test (inf+iNan)*(2/3+i0)  (                      NaN,                   
  NaN)
 cmplx_test  (inf+iNan)*(2/3) (                      NaN,                     
NaN)


-O3 -ffast-math:

 cmplx_test (inf+iNan)*(2/3+i0)  (                +Infinity,
0.66666666666666663     )
 cmplx_test  (inf+iNan)*(2/3) (                +Infinity, 0.66666666666666663  
  )

Which seems to resolve the issue. Closing.
