Evan, Your patch uses an operating system call that is not portable. All non-portable code needs to be located in the lib/System library. I'm not sure why this problem appears on an old Red Hat system. Perhaps the C++ io library is not up to snuff on that platform? What compiler are you using? Reid.

I ran the LLVM regression tests today (via make check) and noticed that llvm-ranlib crashes with a Bus Error on my test system (a fairly old RedHat 9 system), using the latest CVS version. I did some digging and I think I know what the problem is, and I have attached a quick and dirty patch that fixes the problem for me, but I need a suggestion about how it should be integrated properly.

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
