0000670: FIXED: some statistical functions are prone to integer overflow
Running statistical test (t-test, MWU, WSR) with both samples larger than 32768 resulted in 32-bit overflow. Reproducible in ALGLIB for C#, in 32-bit ALGLIB for C++.

Initial report by Jury Gasnikov mentions unequalvariancettest, but several other functions were affected too.
