Stack consistency error while compiling 2.0.0-p0
- vm_exec.h (END_INSN): llvm-gcc may optimize out reg_cfp and cause Stack/cfp consistency error when the instruction doesn't use reg_cfp. Usually instructions use PUSH() but for example trace doesn't. This hack cause speed down but you shouldn't use llvm-gcc, use clang. [Bug #7938]

This sounds because they use Xcode 4.2 with ruby-build which wrongly hacks with CC=cc and it breaks build.
See also https://github.com/sstephenson/ruby-build/issues/290
It will be fixed by ruby-build.
If you don't use ruby-build and not set CC=cc, please comment it.
