Greetings. I'm getting a segmentation fault on the merging phase while 
running the Aug 26th development release. The command is run as such:
     swish-e -v 0 -M avid.index /usr/tmp/avid.index tmp.index
(This same error occurs with the Aug 12/dev-25 release.)

The config files that created avid.index and /usr/tmp/avid.index are 
identical except for the IndexFile directive and the IndexDir directive. 
The index files produced are very small (14653 words and 25359 words, and 
1206 files and 2491 files, respectively).

While running swish-e says that it is "Writing index entries ..." and makes 
it up to the "Writing word data ..." stage before giving a segmentation 
fault. A partial .temp file seems to be produced. Running gdb on the 
binary, I get the following backtrace:

I haven't debugged any further, figuring I'd better check here first to see 
if this is a known problem with a known solution.

Also, it appears that the -v option has no effect when used with -M. It 
prints the same quantity and quality of information no matter what, even 
when "-v 0 " is specified.

Thanks all!

ps. This is on a 4GB, dual-processor redhat 7.3 system, compiling under gcc 
2.96 with 46G of disc available.
