   A deep dive into the manual   
      
   .. the C1 condition code flag is used for a variety of functions.   
   When both the IE and SF flags in the x87 FPU status word are set,   
   indicating a stack overflow or underflow exception (#IS), the C1   
   flag distinguishes between overflow (C1=1) and underflow (C1=0).
