Java Cast Error

When loading the following C code with the cpg, I get an Exception:

int main() {
	size_t count = (size_t)(42);
	return 0;
}

java.lang.ClassCastException: class 
org.eclipse.cdt.internal.core.dom.parser.cpp.CPPASTUnaryExpression cannot be cast to class 
org.eclipse.cdt.internal.core.dom.parser.cpp.CPPASTIdExpression

Whereas the following code can be loaded successfully:

int main() {
	size_t count = (size_t)42;
	return 0;
}

I’m using the cpg and cpg-neo4j from master branch. Can you reproduce the error?

If A is a function pointer, (A)(B) can very well be a call. It’s not more or less unusual to write a call that way than writing a cast like that

Thanks for the fix! Works for me. Yes, the intention was a cast. With includes enabled, the cpg is doing this correctly in both situations. But without the include, we have encountered a C language ambiguity ^^ Interpreting (A)(B) as a function call A(B) seems to me like an unusual coding style. Changing the heuristic to interpret this as a cast would be a better fit in my opinion.
