I'm in the midst of "rebuilding the world," and dosfstools is one of the packages that broke in the middle of the operation :p. My guess is that there is an SSE/MMX-related setting somewhere that this package doesn't paly nice with (as is usually the case with register-referencing compiler errors); all of the pertinent output is included here. Reproducible: Didn't try Steps to Reproduce: (emerge dosfsutils, 2.10) Actual Results: It broke: <snip> make -C mkdosfs all make[1]: Entering directory `/var/tmp/portage/dosfstools-2.10/work/dosfstools-2.10/mkdosfs' gcc -O2 -fomit-frame-pointer -Wall -c mkdosfs.c -o mkdosfs.o mkdosfs.c: In function `_llseek': mkdosfs.c:110: error: can't find a register in class `BREG' while reloading `asm' make[1]: *** [mkdosfs.o] Error 1 make[1]: Leaving directory `/var/tmp/portage/dosfstools-2.10/work/dosfstools-2.10/mkdosfs' make: *** [all] Error 2 !!!

man portage, read about package.keywords It's more fun than what you're doing to USE.
hmmmm, maybe this bug should go to hardened? Looks a lot like #36926
What? Portage has documentation?! :p Yeah, I probably need to RTFM again at some point... cat, sed, and use.desc{,.local} are easier on me, but using portage's features is probably more graceful ^^. But seriously... yes this does look dangerously similar to bug 36926; I'll go ahead and toss it over to the Hardened folks, and see what they have to say.
I confirm this bug with: gcc (GCC) 3.3.3 20040412 (Gentoo Hardened Linux 3.3.3-r6, ssp-3.3.2-2, pie-8.76) glibc-2.3.3.20040420 and USE="hardened pic pie" Bug 36926 either didn't fix it or it was reintroduced somehow.
I don't think this is a hardened issue. I did a ton of research on this error. The following site talks about these types of compiler errors: http://my.execpc.com/~geezer/osd/gotchas/index.htm The difference between this bug and those errors, is that we do not have any inline assembly. This led me to the next step that we probably shouldn't be using the _llseek system call. It's clearly calling up some assembly in the wrong way. If you examine the llseek definition in both dosfsck/dosfsck.c and mkdosfs/mkdosfs.c, you'll see that there's some silliness related to a glibc bug. Well I tracked this bug down, and here's what the deal is: http://old.lwn.net/lwn/1998/0625/glibc.html This bug hasn't been fixed in the way you'd think it would be. Instead, developers are now being encouraged to use lseek64 instead of lseek. Indeed, if you define a function prototype for llseek and use it (which I tried), gcc will warn you to use lseek64 instead of llseek. I went and look as far back as glibc 2.1.3 and I found a working definition for lseek64. I also checked out the latest sourcecode for e2fsprogs. There is quite a bit of discussion on numerous mailing lists regarding this glibc bug related to e2fsprogs. The way they solved it is with some extensive autoconf logic to test for all the different cases of having llseek, having lseek64, already having a prototype, etc. At this point, I feel it's very safe to simply use lseek64. If you're still not convinced, here's a great discussion on the issue that confirms my research: http://www.uwsg.iu.edu/hypermail/linux/kernel/9806.1/0840.html I have attached a patch for the ebuild, a patch to switch to lseek64, submitted this patch upstream, and encouraged the dosfstools maintainer to read this bug. I've tested all this and it seems to work!
Created attachment 34317 [details, diff] files/dosfstools-2.10-lseek64.patch
Created attachment 34318 [details, diff] dosfstools-2.10.ebuild.diff
Interestingly enough, with this patch, we can remove the filter-flags -fPIC. woo! (That is not in my ebuild diff)

Added in dosfstools-2.10-r1.ebuild KEYWORDS="~x86 ~ppc ~sparc ~alpha ~hppa ~amd64 ~ia64" Arch maintainers please test and mark stable.
Marked stable on amd64.
Stable on x86.
Stable on alpha.
I haven't looked into why yet, but dosfsck consistantly generates bus errors on SPARC.
Weeve, Is that <=dosfstools-2.10 || >=dosfstools-2.10-r1 that causes bus errors? All of the above?
Looks like all of the above. Tested all versions currently in portage (2.8-r3, 2.9, 2.10 and 2.10-r1) and they all exhibit the same behavior.
stable on ppc
ia64 is all set
Bug seems to be fixed then.
