Steps To Reproduce

What I did:

  1. Download drush (5.8)
  2. Edit: /usr/local/Cellar/drush/5.8/libexec/includes/context.inc (or anywhere where drush has files)
  3. Add 'drush_print($contexts);' on 410 line before $contexts = drush_context_names();
  4. Run 'drush status' anywhere.

Your stack trace indicates that you ran out of stack space. And this has nothing to do with Xdebug.

There is however a feature in Xdebug that prevents you from doing this - xdebug.max_nesting_level which by default is 100. I think you changed this default as I count at least a 120 stack frames. If you run php within gdb like:

gdb --args php which drush status

and then type on the prompt:

run

and when it crashes:

bt full
zbacktrace

it should tell you where this happened.

Alternatively you can increase your stack size: http://stackoverflow.com/questions/13245019/how-to-change-the-stack-size-using-ulimit-or-per-process-on-mac-os-x-for-a-c-or

Or you can set xdebug.max_nesting_level to a lower value (say 80) and see why drush is using so many stack frames.
