The data stack is a stack of sets. Each set collects
data for a single source file. The data stack parallels the call stack:
each call pushes the new frame's file data onto the data stack, and each
return pops file data off.
The file data is a set whose form depends on the tracing options.
If tracing arcs, the values are line number pairs. If not tracing arcs,
the values are line numbers.
