Niels Dekker	01274cf6ac	value_init.hpp now no longer distinguished between workaround and non-workaround, because many compilers don't do value-initialization well. Fixed copy construction and assignment -- discussed with Fernando Cacciola [SVN r41942]	2007-12-09 22:49:58 +00:00
Niels Dekker	8080673977	Added value_init tests if a copy function of T is called when value_initialized<T> is copied -- a case I hadn't thought of before... [SVN r41919]	2007-12-09 11:53:08 +00:00
Niels Dekker	a470b591fb	Added value_init test for an value_initialized<T> object allocated on the heap. [SVN r41667]	2007-12-03 21:41:59 +00:00

Niels Dekker	42e0001370	Added value_initialized<T> test, having T as aggregate POD struct. In the past, this would have triggered MSVC warning C4345; this warning is now disabled within value_init.hpp, changeset [40088] [SVN r40089]	2007-10-16 17:06:39 +00:00
