C code 'double entendre = 2.2250738585072014e-308;'
generates in the following (incorrect) assembly:
        entendre:
          .t_floating 2.22507385850720138309e-308
the assembler compiles this to  ('objdump --full-contents testfpconst.o')
           0000 ffffffff ffff0f00                    ........      
whereas it should have been
           0000 00000000 00001000                    ........        
Note that the above number is DBL_MIN (I wrote it explicitly to simplify the example).
