We'll need steps to redo the crash, a crash log isn't enough.

I'm unable to reproduce at this point.
When I got the crash I had gone into these steps:

  1. enter edit mode for the shoes in the blend file
  2. rotate, resize, move
  3. go into object mode,
  4. resize the object
  5. Undo by Cntrl+Z several times, then the crash occurred.

However, I just tried to reproduce but couldn't.

Is there a way to enable core dump for blender. I imagine if I give you the core, you should be able to investigate it.
I have set "ulimit -c unlimited", but I don't see blender generating a core dump. I build from the source. Should I build the debug version? would that be more helpful?

never mind. I'm able to generate core files now. I'll make sure to include it in future tickets

We don't normally use core dumps, since we need to be able to redo the problem to ensure it's fixed.
