I don't find a stack dump as useful as the output from a diagnostic/
tracing system I wrote that gets included in most of my code and left 
there after development is finished. Its controllable for the amount of 
tracing detail it outputs and has the ability to capture a configurable 
number of trace messages in a circular buffer and dump them when an error 
is reported.

You can blame my exposure to both the Algol68R compiler and runtime 
system for the tracing style and ICL's George 3 OS for the circular 
buffers:

- if an Algol68R program crashed it produced the most marvellous 
diagnostic report. This showed all currently active variables and their 
contents together with the run history showing not only the procedure 
call stack but the execution path taken through them, something like:

   PROC myproc(arg="cat") called
   int n = 23
   Line 4 - if.. else
   Line 12 - if..then
   Line 34 For executed 8 times
   ....

- When George 3 came unstuck it dumped two circular buffers, one showing 
the last 100 code modules executed and the other showing the last 100 
checkpoints in those modules.  

Both systems made problem diagnosis very simple. Combining them allows me 
to use fairly detailed tracing when bug hunting in a long-running program 
without getting buried in megabytes of trace log: setting the buffer size 
to 100-200 trace points is usually enough to show where a program crashed 
and what earlier event caused the crash.
