This might be a cause for worry. You could have buffer overflows and such that mangled its contents before, when it was on the stack, but won't now because it's a global variable, which get their own segment. But the mangling may still be happening.

If I initialize the entire array xsubi[3] I do not have to move its declaration outside main.
So I think having a huge array but not initializing it completely was having its contents over written which in effect was creating a new seed value. I don't know why the contents were being over written though.

That can be caused by things like buffer overruns.

Sure, I was wondering what was wrong in that isolated small piece of code that was causing buffer overflows..

I couldn't make that isolated scrap of code do what you were describing in the first place.

May be it's my compiler that's over optimizing space usage, I don't know. I've moved ahead.. but it sucks to not know where/how I was screwing up.

Out of curiosity, what platform, OS and compiler were you using?
