hi all,
 this is not a question, it's just a warning/advice!
 i lost 2 weeks looking for the error in my/ROOT's code, which was completely
 useless, since it was an hardware problem:
 
i used to have a lot of non deterministic errors like:
	R__unzip: discrepancy with initial size
	Error in <TBasket::ReadBasketBuffers>: fObjlen = 112932, nout = 0
when running a program.

i also encounted strange things like:
  - internal compiler error (while compiling big things)
  - zipping was ok, but unzipping (sometimes) did not work)
  
well, in my case it was the MEMORY, which was corrupted.
going to a store and spending 30euro for a new RAM solved the problem.

use memtest86 to find memory problems.

ps: reading in newsgroups i also learned that problems of this kind can also
    be related to cach, cpu, cpu-cooling, cable-lenght, ... problems.
    but it always seemed to be a hardware problem, though.
    
so long,
 martin
