A real value times a complex value is done wrong. For example:
 0.0 * ( 0.0 + infinity*I)
 infinity * ( infinity + infinity*I )
where I is an imaginary I

#define _Imaginary_I (__extension__ 1.0iF) /* from /usr/include/complex.h */
#define I _Imaginary_I

clang -v
clang version 3.3 (tags/RELEASE_33/rc3)
