This question as stated is not really appropriate for the mailing list gcc@gcc.gnu.org, which is for the development of GCC itself. This question would be appropriate for gcc-h...@gcc.gnu.org. Please take any followups to gcc-help. Thanks. This has nothing to do with using the register keyword. Yes, you should ideally be told when a value is unavailable. This specific area of GCC has been much improved since GCC 4.5.2. > Also, using -fvar-tracking, i get this output while debugging the same > code. That looks like better output to me. Ian
