Incorrect results and segfault while searching using trunk version.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create an index with a June snapshot
2. Search the index with the current trunk branch.
3. No results for "c b" and segfault for "a j g"

What is the expected output? What do you see instead?
For the first search expected 267 results (June snapshot gave that number)
and definitely not a segfault.

What version of the product are you using? On what operating system?
Noted above. On linux with a clustered setup (indexer and search engines
seperated).

Please provide any additional information below.

If you use newly introduced opion --enable-multidbaddr for configure with 
current 
trunk branch, try rebuild without this option. Will you get segfault then ?

Hello,

Looks like the same results with or without the multidbaddr enabled.

Please check out and try fresh version from the svn trunk.

Still same thing. Will try it out more later.

Please try fresh snapshot as of July 15, there were some memory problems fixed.
As well, you can check out from the svn repository.
