Greg-
not that I am trying to be a PITA but where did you get the information that initialized variables live in .bss?
Initialized variables live in .data, the .bss (Block Started by Symbol) is reserved for non-initialized variables.
Look: visitor@satelite:~> cat a.c int first_var; int second_var = 5; visitor@satelite:~> gcc -S a.c visitor@satelite:~> cat a.s .file "a.c" .globl second_var .data .align 4 .type second_var,@object .size second_var,4 second_var: .long 5 .comm first_var,4,4 .ident "GCC: (GNU) 3.2" visitor@satelite:~>
