Re: TMath::Sort :: warning if n < array size

Hi Adrian,

Thanks for your suggestion. We can't determine the sizeof(index), all we have is a pointer (not an array), and that would just return you sizeof(void*).

A recommendation: you could have used valgrind to find this problem in your usage of Sort().

Cheers, Axel.
