When I compile an executable twice use command "/opt/SUNWspro/WS6U2/bin/cc -g" at he same time, and then use "diff" command to compare this twice output file, I found that they are different.
After use "strip" command to strip this two files, they are different also.
Why?

Dear MaximKartashev ,
Thanks very much!
When use "-g" option, the executable file sould be different after twice compilation, even we use "strip" command.
Right?

As far as I understand, no, but that is only true if you don't use optimization.
