Actually, competitive pressures make even this small cost unacceptable in
some cases (especially leaf procedures). However, it is possible (if one
is sufficiently determined and can get the compiler and debugger folks to
work together) to associate a table with the code ("code header" or
"traceback table") which gives the debugger the necessary clues for
unraveling the stack.
