This looks like your bug, not neither LLVM nor clang bug. You cannot
use the LLVM's casting functions with non-LLVM types.
Here it seems you're doing something like cast<uint64_t>(foo), where
foo is 'long'

Consider reading http://llvm.org/docs/ProgrammersManual.html#isa for
more information (especially the last paragraph).
