Hello, Three months ago I sent this mail to gcc-help: http://gcc.gnu.org/ml/gcc-help/2011-03/msg00064.html The behavior in gcc 4.6 release persists. I don't know if it is a bug exactly (in the original mail, some says that is a bug and some no). Thanks -- ***************************************** José Luis García Pallero jgpallero@xxxxxxxxx (o< / / \ V_/_ Use Debian GNU/Linux and enjoy! *****************************************
