The llvm_string_of_message function, called by llvm_raise, calls LLVMDisposeMessage, which expects the message to be dynamically allocated; it fails freeing the message otherwise. So always dynamically allocate with LLVMCreateMessage. Differential Revision: http://reviews.llvm.org/D18675 llvm-svn: 265116
