Exception#backtrace has the entire stack in it: def do_division_by_zero; 5 / 0; end begin do_division_by_zero rescue => exception puts exception.backtrace raise # always reraise end (Inspired by Peter Cooper’s Ruby Inside blog)
While debugging, Go to Debug -> Windows -> Call Stack
Something along the lines of StringWriter errors = new StringWriter(); ex.printStackTrace(new PrintWriter(errors)); return errors.toString(); Ought to be what you need. Relevant documentation: StringWriter PrintWriter Throwable
Andrew Grant’s answer does not help getting a stack trace of the throwing function, at least not with GCC, because a throw statement does not save the current stack trace on its own, and the catch handler won’t have access to the stack trace at that point any more. The only way – using GCC … Read more
import traceback traceback.print_exc() When doing this inside an except …: block it will automatically use the current exception. See http://docs.python.org/library/traceback.html for more information.

I have module I use for situations like this – where a process will be running for a long time but gets stuck sometimes for unknown and irreproducible reasons. Its a bit hacky, and only works on unix (requires signals): import code, traceback, signal def debug(sig, frame): “””Interrupt running process, and provide a python prompt … Read more
Here’s an example of getting the stack via the traceback module, and printing it: import traceback def f(): g() def g(): for line in traceback.format_stack(): print(line.strip()) f() # Prints: # File “so-stack.py”, line 10, in <module> # f() # File “so-stack.py”, line 4, in f # g() # File “so-stack.py”, line 7, in g # … Read more
Have a look at the System.Diagnostics namespace. Lots of goodies in there! System.Diagnostics.StackTrace t = new System.Diagnostics.StackTrace(); This is really good to have a poke around in to learn what’s going on under the hood. I’d recommend that you have a look into logging solutions (Such as NLog, log4net or the Microsoft patterns and practices … Read more
