For line numbers the #line directive should also affect the debugging
info, no?


Concerning data, you would have to teach the debuggers a lot about
your source language even if you can give it information about
source-level data and variable, right?

Typically with print-statement debugging. I also found backtraces
quite useful, whereas gdb-style debuggers are often a way to waste a
lot of time (let's step a little further, maybe the bug will show up
here); and when I find them useful, I typically want to see stuff at a
low level (typically machine-level), anyway, but that may just be due
to the things I program.
