Correctly zero-initialize MainThread It can be used uninitialized in time management. Fixes all valgrind errors on './stockfish go wtime 8000 btime 8000 winc 500 binc 500' This is one (of the many) quirks of C++. There is a subtle difference between: new Foo new Foo() The first statement calls the default constructor (that in case of a POD leaves data members uninitialized), the second one performs a value-initialization (that in case of POD is equivalent to a zero-initialization) See: http://stackoverflow.com/questions/620137/do-the-parentheses-after-the-type-name-make-a-difference-with-new http://stackoverflow.com/questions/5116541/difference-between-creating-object-with-or-without No functional change.
