I believe Xcode 4.1 has been out since an iOS 4.x release. Xcode
4.2 is still in beta as it is bundled with iOS 5 beta. There is
a strong chance that the gnu toolchain in that release could our
culprit, akin to Russ' suspect of getcontext/setcontext. It may
also be that the 4.1 release was the first one where llvm-gcc was
also an option. My other build issue is in libstdio:
% 9c -v dtoa.c
Using built-in specs.
