It's uic segfaulting. 1) You have silly CFLAGS which could very well be causing all this 2) Who knows what patches you have to your kernel.. 3) You need to update your profile to a 2006.1 profile.. (eselect profile)
Upgrade your toolchain, recompile stuff, use a supported kernel, drop stupid C[XX]FLAGS... http://www.gentoo.org/doc/en/gcc-upgrading.xml If you still have issues then, file a new bug.
Since this was "resolved test-request," and I've done some testing, I'm reopening it. I've cut my flags back to the basics, updated most everything else in world outside of KDE (including the profile), and re-emerged first qt (to have uic emerged with the basic flags), and then attempted kdebase. It still segfaults in the same place: /bin/sh: line 3: 7520 Segmentation fault /usr/qt/3/bin/uic -L /usr/kde/3.5/lib/kde3/plugins/designer -nounload -tr tr2i18n -i main_buttons_widget_ui.h ./main_buttons_widget_ui.ui >main_buttons_widget_ui.cpp.temp This is consistent over three attempts. Now, I have not upgraded gcc past 3.4.6-r2, since going to gcc 4 would require days of rebuilding most everything on the system. If gcc 3.4.6 is no longer supported under Gentoo, I've missed that notice. I also am still running the same kernel, which is nothing more than a stock kernel with the Win4Lin patches. But in 14 years of compiling stuff under Linux I've never seen a compile failure where the kernel was at fault. Have you? An aside on "silly" and "stupid" cflags: my former flags where those which have in the past been generally agreed in the Gentoo forums to be the most sensible and safe for improved performance. Obviously Doug and Jakub, you disagree with that consensus - which is fine, nothing wrong with testing with simpler flags. I can now say for sure it's not the flags. That's a step forward. If you really have cause to suspect the kernel version, I can switch for the purpose of compilation testing. Nothing else has failed among hundreds of compilations under this kernel, so I'll bet that's not it. But I can be wrong. If you really don't like gcc-3.4.6 - well, isn't that still the official version for Gentoo Hardened? Seems to me like current packages should be required to compile cleanly under any of the last several gcc versions.

Jakub, Please let someone else evaluate this. I know from long experience with you that you "really don't care much" about anything but closing bug reports on any excuse you can find that doesn't involve anyone actually fixing the bugs reported. Or at least answer my specific question: Does Gentoo still support gcc 3.4.6 or not? Because it's still in portage, and everything else in my current "world" builds fine with it except kdebase. So what's the official policy on gcc 3.4.6 support? If the policy is to support it still, then this bug report should be addressed, not shuffled aside.
Please cd to /var/tmp/portage/kde-base/kdebase-3.5.6-r1/work/kdebase-3.5.6/khotkeys/kcontrol/ui and run the uic command line manually. Does it segfault again? (It should.) If it does, please strace it and attach a log to this bug. (And please refrain from attacking other devs.)
Wulf, Appreciate your engaging this. No segfault here, either from just running "uic" there (which just waits), or in running the line that was reported with the segfault in the ebuild: /var/tmp/portage/kde-base/kdebase-3.5.6-r1/work/kdebase-3.5.6/khotkeys/kcontrol/ui # /usr/qt/3/bin/uic -L /usr/kde/3.5/lib/kde3/plugins/designer -nounload -t Qt user interface compiler. uic: Unrecognized option [then the syntax specs] Is there some other way you want that entered? (The other developers were disrespectful first - just saying.)
Sorry, this somehow escaped my attention. Is this still a problem with 3.5.6-r3 or 3.5.7?
I maintain a system at work using GCC 3.4 to build everything and KDE has no problems there. Some CFLAGS applied globally can cause segfaults and with things like this everything that links to the binary segfaulting can also cause issues. You can also get issues if a big compile is causing heating issues or revealing a problem with RAM - I have encountered this once or twice in the past... I have not been able to reproduce your issues on my GCC 3.4 system or my GCC 4.1 systems. I personally would recommend upgrading your toolchain and rebuilding world with safer CFLAGS. It is not enough to just rebuild qt but these issues can be tough to track down. If we cannot replicate them then it makes it very hard to be certain it is not something like a hardware issue or side effect of aggressive CFLAGS. It has been nearly a month since Wulf asked for more details - please reopen if this is still an issue with KDE 3.5.7.
