GCC gives all information it has to the debugger. It's up to the debugger
to make best use of it. But GCC can't invent information that does not
exist any more. An incoming argument register that is subsequently
resused for something different simply does not contain the original value
any more.

Export CFLAGS=-O0 and most (if not all) GNU packages will use -O0 as their
default builds.
