Comment (by slyfox):

 One more note:

 The bug you describe should surface on amd64 if you change return type
 from 'int' (%rax) to 'double' (%xmm0) in your example, correct? On
 gcc-5.3.0/amd64 it seems to work as expected:
 {{{
         call    double_returning_function
         cvttsd2si       %xmm0, %eax
         cmpl    $42, %eax

 }}}
