[cfe-dev] Constants.cpp assertion raised

[Michael Zolda]

Hi!


Here is another piece of code that causes a crash (current SVN version):

typedef struct {
  unsigned char c;
} t;

const t x = { 1 };


Output:

clang: /home/michaelz/proj/fortas/source/external/llvm/lib/VMCore/Constants.cpp:377: llvm::ConstantStruct::ConstantStruct(const llvm::StructType*, const std::vector<llvm::Constant*, std::allocator<llvm::Constant*> >&): Assertion `(C->getType() == T->getElementType(I-V.begin()) || ((T->getElementType(I-V.begin())->isAbstract() || C->getType()->isAbstract()) && T->getElementType(I-V.begin())->getTypeID() == C->getType()->getTypeID())) && "Initializer for struct element doesn'tmatch struct element type!"' failed.
