RobotC 4.27 Pointer bad syntax? or bug?

Hello, came across something today, was curious if I was just doing something stupid or if there is a bug here. (On RobotC 4.27 for VEX)


	Code: int* foo(int* f) { return f; } task main() { int x = 65; int* ptrx = &x; int x2 = *foo(ptrx); }

This code doesn't compile with the following error:


	Quote: 11: Warning:Internal Compiler: '' (Pointer dereference) operator is not valid at this point 11: Severe:Internal -- trying to emit for undefined variable

Shouldn't foo return a pointer that I could then dereference?

The following code works:


	Code: int* foo(int* f) { return f; } task main() { int x = 65; int* ptrx = &x; int* ptrx2 = foo(ptrx); int x2 = *ptrx2; }

Is this not allowed in C? Is there something silly I'm missing? Is this a bug in RobotC? Curious what others think. The hope is to be able to return a pointer of an arbitrary type in one line.
