[cfe-dev] A problem about builtin-type creation

[peterlee]

Dear All,

I am using Clang/LLVM-3.3, at present, I am fixing an error about 
creating a builtin type, the code is supposed to
generate a "boolean" type with the following code:

clang::Type* bool_type = new 
clang::BuiltinType(clang::BuiltinType::Bool);
params.push_back(klimt::NamedDecl(clang::QualType(bool_type, 0), 
pname));

I always encountered the error:

/home/xxx/vendor/llvm-3.3/build32/Release+Asserts/../../include/llvm/ADT/PointerIntPair.h:100: 
void llvm::PointerIntPair<PointerTy, IntBits, IntType, 
PtrTraits>::initWithPointer(PointerTy) [with PointerTy = void*; unsigned 
int IntBits = 1u; IntType = bool; PtrTraits = 
llvm::PointerUnionUIntTraits<const clang::Type*, const 
clang::ExtQuals*>]: Assertion `(PtrWord & ((1 << 
PtrTraits::NumLowBitsAvailable)-1)) == 0 && "Pointer is not sufficiently 
aligned"' failed

The assertion fails at the BuiltinType creation.

Any thoughts about how to fix this error is highly appreciated!

Thanks
Peng
