Once again: you're seeing that compiler-rt build is broken. This seems to be
due to assertion in clang. Which is triggerred (most probably) due to
miscompilation of *clang* by your system gcc. So it does not help whether
you're using "clean checkout" or something else.

> This gcc (4.1.2) works fine (was working all day today).
Note the following line from the link I posted:
"GCC 4.1.2 20071124 (Red Hat 4.1.2-42): Suffers from the same symptoms as the
previous one. It appears to work with ENABLE_OPTIMIZED=0 (the default)."

So, some RedHat-provided version of gcc (which appears to be the same version
of yours) is already known to be broken.

Before reopen please try two things:

1. Check the debug build (make ENABLE_OPTIMIZED=0) of llvm/clang
2. Check with other version of gcc (not 4.1.x at least)

If this is still reproduces with 2. - then please reopen. Otherwise, please
upgrade your gcc.
