While trying to compile an LLVM IR, like this
llc main.ll -o main.s && g++ main.s -O3 -o main -pthread
I get the following error. The same thing compiles on my Ubuntu 10 system, but in the CentOS I get the following error. Any idea what is going on here and why LLVM is going mad? And lastly, how to solve this?

Looks like LLVM is miscompiled by your system compiler. See http://llvm.org/docs/GettingStarted.html#brokengcc for a list of known broken compilers.
The solution is simple – use other version of the compiler (gcc in your case) to compile LLVM.
