memory - How to let gcc actually allocate variables instead substituting with symbols? -

-

i noticed if have variables defined char = 'a'; or char a; = 'a'; or char a; = 'a'; = 'b';, , try print a in gdb, tells me no symbol "a" in current context.. apparently gcc, during compilation, optimizes a character constant, instead of char variable holding value.

how tell gcc not trick, treat a variable (allocate memory , assign character value memory)?
