This file contains a shell script an the failing C code.
I get an error using a recent (r248677) TOT.
I was originally compiling the libedit library for several targets (ARM, Mips,
etc.) It seems to fail for all architectures. I have simplified the error
causing code using clang for x86_64 (test case attached).
Here is the error:
lang: /home/rich/llvm/include/llvm/Support/Casting.h:237: typename
llvm::cast_retty<X, Y*>::ret_type llvm::cast(Y*) [with X = llvm::IntegerType; Y
= llvm::Type; typename llvm::cast_retty<X, Y*>::ret_type = llvm::IntegerType*]:
Assertion `isa<X>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
