      Description

      Running this on my Mac dumps core:

      % mkdir WT_TEST
      % ./wtperf -O ../../../bench/wtperf/runners/multi-btree.wtperf
      wtperf(58301,0x7fff7d7e9180) malloc: *** error for object 0x7f8670c03eb0: pointer being freed was not allocated
      *** set a breakpoint in malloc_error_break to debug
      Abort (core dumped)
      

      It does not fail on AWS/linux.

          It appears this happens at the end of the test.

          Message: WT-2783 Clean up wtperf configuration object management (#2957)

          The multi-database wtperf feature implementation assigns memory from the
          base CONFIG structure to the CONFIG copies, but then individually frees
          the memory referenced by the copies, resulting in OS X complaints that
          memory is freed more than once.

          Rename the config_assign() function to be config_init(), it does more
          than simply assign the previous values.

          In config_init(), create copies of the configuration strings in each new
          CONFIG structure. There are also a few places where CONFIG.home and
          CONFIG.monitor_dir are set (for example, to the value of the command
          line -h and -m options), change that code to free/allocate so we maintain
          a local copy of the strings in every CONFIG structure.

          Change config_init() to copy the CONFIG.home and CONFIG.monitor_dir
          fields along with the rest of the CONFIG structure, they get freed in
          config_free(), so they should be copied in config_init().
