opt: llvm/lib/VMCore/Instructions.cpp:2356:
llvm::TruncInst::TruncInst(llvm::Value*, const llvm::Type*, const std::string&,
llvm::Instruction*): Assertion `castIsValid(getOpcode(), S, Ty) && "Illegal

Here's the testcase:
%wrapper = type { i1 }
define void @f() {
entry:
%w = alloca %wrapper, align 8 ; <%wrapper*> [#uses=1]
%0 = getelementptr %wrapper* %w, i64 0, i32 0 ; <i1*>
[#uses=1]
store i1 true, i1* %0
ret void
}
