      Description

      I was archiving the revised test from 5003341 when I ran it on Mustang/6.0
      bits instead of on Tiger/1.5.0 bits. To my surprise, the test crashed. Here
      are snippets from the doit logs from both product and fastdebug bits:

      Here is a stack trace snippet from the product bits crash (SIGSEGV):

      The testcase is attached as testcase.tgz. The various logs are attached as logs.tgz.
      Also reproduced with Dolphin-B11 bits. Looks like the same crash
      and assertion failure, but I didn't generate thread dumps and stuff.
      The failure does not reproduce with Tiger/1.5.0_08 bits on my laptop
      or with Tiger/1.5.0_12 bits on producer.
