Check your FEATURES, you might have "strict" or "stricter" in there. Ie, you asked portage to die on QA errors.

Could you paste the output of emerge --info?

Thanks

[Comment 4 Mart Raudsepp 2008-07-12 10:43:34 UTC]

From his build environment attachment:

FEATURES='ccache collision-protect cvs digest distlocks fixpackages metadata-transfer multilib-strict parallel-fetch sandbox sfperms sign splitdebug strict stricter unmerge-orphans userfetch userpriv usersandbox'

stricter probably makes it die? We need to get that crap to not cause QA dies as they aren't a Gentoo QA problem, but that's a more global matter than this particular "bug"

[Comment 5 Péter Werner 2008-07-13 21:45:34 UTC]

Yes, this is all about a QA warning that causes the build to fail if FEATURES has stricter, which is on by default in the new 2008.0/developer profile.

Do you really need emerge --info?

[Comment 6 Gilles Dartiguelongue (RETIRED) 2008-07-16 07:14:03 UTC]

sorry but this kind of errors ("dereferencing type-punned pointer will break
strict-aliasing rules") are to be handled upstream. FEATURES="stricter" is a developer feature imho and shouldn't be enabled by users. This is why it is in the developer profile. You can always disable it in your make.conf.

[Comment 7 Péter Werner 2008-07-19 06:47:53 UTC]

No problem for me to work it around.
I just assumed that with 2008.0 Gentoo wants to collect QA problems.  There was a message asking it, but perhaps I missed "upstream" in that.
(I assumed developer is a profile for people using the PC for development not for Gentoo devs.)
Sorry for making an invalid bugreport.
