The 19 October 2007 build (4545) is out.

I'm pretty sure it is a problem with openSUSE 10.3 and not Code::Blocks as i also started getting this problem right after upgrading to 10.3, i set up a virtual machine with 10.2 to test against Code::Blocks svn build 4565 and its all tea and biscuits.

A bug report needs to be sent to the openSUSE development team, but that would require some hard facts about the problem (i.e. an actual bug report) which i wouldn't have the faintest clue how to get or where to start looking.

Sigh... I really must be unlucky, I got this bug ('forced rebuild on compile') too.

It's really hard to report it indeed...
My gcc is 4.2.1 too (under Debian).

I don't have any problem under Gentoo where gcc version is older (I'll reboot to make it clear).

*rebooting*

Indeed, my Gentoo's gcc version is 4.1.2.
That said, Code::Blocks version is 1.0_pre20070618, thus it's really hard to say which of CB or gcc is incriminated...

Perhaps try older and newer revisions of C::B, if you every find it used not to happen and later started happening you can do a revision search
