BRL-CAD's primary geometry editing tool is called 'mged'.  What's more frustrating than software crashes?  We put a lot of emphasis on developing quality software so see if you can find a problem.

Find a way to crash mged reliably.  You must compile our latest Subversion sources, run mged, and keep track of steps taken that cause a crash.  If you can provide a stack trace, even better.  You must submit specific conditions and steps that will reliably and reproducibly cause a crash.

It must be a bug that is NOT already documented in our BUGS or Sourceforge bug tracker nor be a bu_bomb() graceful termination.  It might help to become minimally familiar with how to run mged as the interface is not at all newbie-friendly.
