test case run script generated by clang
testcase:
struct st
{
int m1;
int m2;
} obj;
struct st foo ()
{
return obj;

Crash backtrace:
clang: /home/parallels/code/llvm-project.git/llvm/lib/IR/Constants.cpp:2028:
static llvm::Constant* llvm::ConstantExpr::getBitCast(llvm::Constant*,
llvm::Type*, bool): Assertion `CastInst::castIsValid(Instruction::BitCast, C,
DstTy) && "Invalid constantexpr bitcast!"' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
