Can there be parallel initialization of global variables in C++0x?
in [C++]

From: DeMarcus on 27 May 2010 04:08 Hi, As the standard now defines multi-threading, is there anything said about the initialization of global variables? I.e. will a compiler be allowed to initialize global data in parallel? Thanks, Daniel -- [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

For example, within a single translation unit objects with static storage duration must be initialized in order of definition.
