Hi List,


I am coding some protocol, and when I want to print a value of a local
variable within GDB, I get this:

Cannot access memory at address 0x80000417caef

I found out that this happens when GDB wants to access a variable which is
out of the scope of the process. However, this is a local variable. When I
set the variable to static, it works. I compile the code with

-O0 -gstabs+ -g3 -Wall.

My gcc is

Using built-in specs.
