   From 'man nasm' I quote:   
   ==quote==   
    -F format   
              Specifies the debug information format. To see a list of valid   
   output formats, use the -y option (for example -felf -y).   
      
          -g   
              Causes nasm to generate debug information.   
      
          -gformat   
              Equivalent to -g -F format.>   
   ==unquote==   
      
   When I tried your suggestion I got the same result:   
   (gdb) break 8   
   No line 8 in the current file.   
      
   So i tried -gdwarf   
      
   Same result.   
      
   Maybe I should also give the linker some options to handle debug information   
   (?)   
      
      
   Anyway....I'm off for familiy matters.   
      
   I'll try further tomorrow
