      Description

      Can be reproduced running test/format with the following config:

      ############################################
      #  RUN PARAMETERS
      ############################################
      # bitcnt not applicable to this run

      # wiredtiger_config not applicable to this run
      write_pct=5
      

      I've also seen a different failure with the same config file:

      format $ ./t -c config7 
      t: process 13884
      file:wt-000019.lsm: ../src/bloom/bloom.c, 263: bloom->bitstring == NULL7673
      file:wt-000019.lsm: aborting WiredTiger library
      

      The run directory contains:

      format $ ls -l RUNDIR/
      total 1200
