--- Comment #15 from Maggioni Marcello hayarms@gmail.com 2011-06-07 11:46:29 PDT --- Yes, you are perfectly right, I looked better to the application and you are right, but considering that you don't set the "random seed" value with srand the random sequence is always the same, so the first execution of the of the "while" cycle should always have the same 68698 samples drawn. So at least in the first cycle my test app should report
Correct: 50 Non correct: 0
right?
This is an example of a sequence of values reported in the first cycle:
Param is: 68698 Param is: 2147483647 Param is: 2147483647 Param is: 2147483647 Param is: 2147483647 Param is: 68698 Param is: 2147483647 Param is: 68698 Param is: 68698 Param is: 2147483647 Param is: 68698 Param is: 68698 Param is: 68698 Param is: 2147483647 Param is: 2147483647 Param is: 2147483647 Param is: 2147483647 Param is: 68698 Param is: 68698 Param is: 68698 Param is: 68698
The patch is applied, of this I'm sure.
I tried reducing the value of the "size" variable (as you suggested) to 16 (instead of the value that usually is set by num_results that is 32), and the result is :
Param is: 34594 Param is: 2147483647 Param is: 34594 Param is: 34594 Param is: 34594 Param is: 2147483647 Param is: 34594 Param is: 34594 Param is: 34594 Param is: 34594 Param is: 2147483647 Param is: 34594 Param is: 34594 Param is: 2147483647 Param is: 34594
The correct values are almost half of the ones with "size = query->num_results" and the non correct ones are the same ...
It seems like the memory gets corrupted or not correctly initialized sometimes.
Any idea?
