-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 It's not a compiler bug.
Basically the C++ standard does not enforce an initialization order for globals. So the compiler is free to initialize such stuff in any order. I think your toolchain just happens to be lucky enough to do that in an the order which doesn't yield in a crash. I don't have the time to look this up in the C++ standards myself, but you can google such stuff: http://stackoverflow.com/questions/3746238/c-global-initialization-order-ignores-dependencies Blessings, Jaak On 10.09.2013 18:12, Troy A.
