I found that if there is another similar object in this file which is referenced externally, then the constructor of my_instance is also called, even if it is marked static, and has no references. I have gcc 4.3.1 on SuSE 11.0 uname -a Linux notebook 2.6.25.18-0.2-pae #1 SMP 2008-10-21 16:30:26 +0200 i686 i686 i386 GNU/Linux Thanx K. Gy.
