Unfortunately, I haven't been able to figure out the cause of this. As far as I can tell, something about the current NPTL glibc build causes sandbox to do weird things. This has also been discussed at http://www.nabble.com/Re:-problem-upgrading-the-toolchain-p1874985.html though no solution is apparent. I'm using vanilla-sources-2.6.13.1, sys-devel/gcc-3.4.4-r1, sys-devel/binutils-2.15.92.0.2-r10, sys-libs/glibc-2.3.5-r3 (+nptl -linuxthreads-tls) and CFLAGS="-mieee -O2 -mcpu=ev6 -pipe -fomit-frame-pointer" I'd love to provide more information about this, so please ask. I will comment that this system has not been rebooted since the glibc upgrade...

(In reply to comment #4) > sandbox works fine for me and I'm running alpha glibc+nptl. The only difference > in our glibc USE flags is that I also have nptlonly. Thanks for the suggestion, I was a little afraid to try it, since the NPTL part didn't work. I just did though, and everything works fine now. *weird* If anyone has any suggestions about finding the cause, I could try some things out, but I'm a little less inclined to test now that it works, and glibc (esp without nptlonly) isn't the fastest of packages to compile.

I don't think there's much hope this will be fixed upstream as linuxthreads is no longer supported. Instead, we've been forcing +nptl +nptlonly in the 2006.0 profile to avoid this problem.

Now why did having both NPTL and non-NPTL glibc cause sandbox to do weird things, while the regular system env worked fine? Is the bug well understood? If so, could you elaborate/add a link? If not, why are you blaming linuxthreads?
No, the problem only exists on +nptl -nptlonly systems. Mixed systems if you want, where both nptl and linuxthreads is enabled. If you stick to either nptl or linuxthreads this problem doesn't exist at all. That's why we now have a (default) nptlonly profile and an no-nptl profile for users wanting a linuxthreads system. In effect I'm not blaming either nptl or linuxthreads but we've spend considerable time trying to fix the mixed situation but upstream doesn't want to look at it at all. As linuxthreads is effectively unsupported upstream we're not going to get a better solution than what we've already implemented.
ok, the ppc fix we put in place also works here so i'll update our glibc ebuilds so people can use "nptl -nptlonly"
