Re: [CLucene-dev] RAMDirectory testing (using MockRAMDirectory)

[Itamar Syn-H. <it...@co...>]

Borek, the intensive_testing branch is consistently crashing in one of 
the IndexSearcher tests, with an AV / buffer overrun. I'm testing with 
VC8. Is it something you have seen already?

Since it seems to be related to threading, I merged master and then 
atomicthreads with your branch to see if that will resolve the issue, 
but it didn't. You can find it under 'intensive_testing_merged'.

Let me know what you find.
