a quite short answer
all i can safely identify is a error message from gdb about an non-existing file which exists in exactly that spot.
I already 777'ed the whole file structure to eliminate a error source to no avail.
I can, however, not say if this is a gdb problem or a C::B Problem, as i haven't had the time yet to probe around on the issue.
I do see the same pattern as "Eremit", though so i thought I'd second.
