Your message should probably have been sent to [EMAIL PROTECTED] rather than to [EMAIL PROTECTED] You may or may not have found a bug in the compiler. It's fairly common for incorrect code to work as expected with some set of options and fail with a different set of options. However, since you are using uncommon options, it could certainly be a compiler bug. Filing a bug report could be helpful, but in order for us to do anything with it you will need to provide quite a bit more information. For the kind of information we need, please see http://gcc.gnu.org/bugs.html . Thanks. Ian
