-mno-ieee-fp -march=i686 gives internal error

[Ole Tange]

Compiling

#define todB(x)   (*(x)==0?-400.f:log(*(x)**(x))*4.34294480f)
static float _ve_deltai(void){
  float A=0;
  A=todB(&A);
}

with both -mno-ieee-fp and -march=i686 gives internal error. If either
option is removed the compilation finishes without errors.
