This seems to be caused by -finline-functions in CFLAGS... normally I'd say INVALID for goofy CFLAGS, but that one is in -O3 and I *think* I've been told that -O3 build bugs are valid. Anyway, you can work around this issue by removing that from CFLAGS. The maintainers can decide if this is a valid bug or not.

Someone much more qualified than myself will have to figure out exactly which flags are triggering this, but I believe you can reproduce/workaround this by manipulating CFLAGS. -Os fail -O1 success -O2 success -O3 fail -O3 -fno-inline-functions success
In my opinion the issue is more due to the presence of -Werror=uninitialized than with your choice of CFLAGS. As you noted, -O3 implies -finline-functions, and -O3 is a reasonnable flag, even if not always optimal. All those -Werror compile options need to be stripped from the build system. Denis.
Created attachment 369520 [details, diff] Build fix for mit-krb5-1.12.1 Oh well, new ebuilds should be tested with -O3 or the -Werror stuff stripped from the ebuild.
Created attachment 372942 [details, diff] uninitialized.patch The problem appears to be that gcc doesn't realize that gettimeofday is guaranteed to set errno to non-zero on failure. Sticking an assert in fixes the issue at source.
Created attachment 372968 [details, diff] krb5-1.12.1-Wuninitialized-initializations.patch There are more places which reports the same failure. The attached patch applied over the current ~app-crypt/mit-krb5 allows it to be built.
I can confirm the patch from #8 fixes my build problems.
Fixed without revbump. + 26 Mar 2014; Eray Aslan <eras@gentoo.org> + +files/mit-krb5-1.12_warn_cflags.patch, mit-krb5-1.12.1.ebuild: + Do not build with -Werror - bug #498794 +
