I have no special dissectors or plugins - it's a generic installation.

It works fine (same parameters and trace file) on 1.4.6 and 1.6.10 on this OS. 
It fails under 1.8.1 and 1.8.2.  Here's the memory footprint for the successful
run on 1.6.10:

  PID USERNAME    THR PRI NICE   SIZE    RES STATE    TIME   WCPU COMMAND
46024 steve         1  73    0 91396K 51144K RUN      0:01  0.00% tshark

Built using gcc 4.2.1 20070831 patched [FreeBSD].
=======================
Memory usage on 1.8.2 *without* "-z io,stat,1" (which works fine):

  PID USERNAME       THR PRI NICE   SIZE    RES STATE   C   TIME   WCPU COMMAND
32522 steve            1  22    0 70952K 30280K CPU1    1   0:00  0.59% tshark
=======================
Also, I ran the tshark 1.8.2  with a 10 second io,stat interval rather than 1
second (tshark -n -r 20120214-BA_00001_20120214155239.pcap -q -z io,stat,10)
and the memory footprint is much smaller, but it still coredumps:
