llvm dev - Jan 2012 - [LLVMdev] Cast error

Hi all,

I have a trouble with LLVM rev - 147926 cast instructions. Here is my code:

............
for(std::vector<Value*>::iterator it = getElementPtrs.begin(); it
!getElementPtrs.end(); ++it) {
                 Value* current = *it;
                 errs() << *current << "\n";
                 GetElementPtrInst* gep =
cast<GetElementPtrInst>(current);
                 assert(gep != NULL && "GetElementPtrInst must be
valid!");
............

Program crashes with the above mentioned assertion. Here getElementPtrs is
a vector of Values, that are GetElementPtrInst- s. errs() works fine. I've
also tried to dyn_cast the value, but it doesn't work too.
Any ideas?

Sincerely,
Hripsime.

maybe it's a ConstantExpr getelementptr, rather than a GetElementPtrInst?

Ciao, Duncan.
