some gdb problem.

Hi zouq,

>who can tell me the reason?

Do this command:
gdb --version

If it doesn't say 6.3, then go here, download, compile, and use gdb-6.3:
http://directory.fsf.org/GNU/gdb.html

If it does say 6.3, then I'm not sure.  Are you compiling using "-g", "-g3", "-ggdb", "-ggdb3", or something else?

Check out "man gcc", and go to the "Options for Debugging Your Program or GCC" section.

HTH,
