The missing location is strange, since you're compiling without
optimization; that's probably a bug. But it's a separate bug that
they don't show up in the list; I'd rather fix dwarf2read.c than the
test.
IIRC the problem is that we use different LOC_* values for function
arguments. I have a patch somewhere that used a different mechanism,
so that we could mark arguments as LOC_OPTIMIZED_OUT. I'll try to port
it to the current GDB next week.
