[zeromq-dev] mdp_broker sample is crashing [ Are there any known issues when running on 32 bit Ubuntu ? ]

Hi All:

I'm running the (pure vanilla) mdp_broker with the matching clients and
workers.
The broker is failing and dumping as soon as I start the first worker.
(see verbose feedback below)

I believe the libs are built successfully, using the latest source,
all on my 32 bit Ubuntu server:
  > libzmq
  > libczmq
  > libmdp

The worker seems good.  It connects, performs heartbeating, etc.
The broker fails almost immediately when the worker connects.

Before going any further, I thought I would ask whether there is any
obvious advice.
Like, for instance, "don't bother trying this on a 32 bit machine".
Or "there is a patch for this".

Thanks for any guidance while I fire up the debugger.
