<pre>The following code:
void test(int a)
{
#pragma omp target map(a)
#pragma omp parallel
{
a = 1;
}
}
compiled with "clang -fopenmp -c map-crash.c" gives me
void llvm::CallInst::init(llvm::FunctionType *, llvm::Value *,
ArrayRef<llvm::Value *>, ArrayRef<OperandBundleDef>, const llvm::Twine &):
Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) ==
Args[i]->getType()) && "Calling a function with a bad signature!"' failed.
Removing the explicit map works fine, but the scalar is then firstprivate by
OpenMP 4.5. defaultmap(tofrom:scalar) surprisingly does not crash either, but I
wonder if its codegen is actually already implemented (I haven't tested the
behaviour).</pre>
