V9002¶

The VM attempted to pop from an empty operand stack. This is an internal error indicating the compiler emitted unbalanced push/pop sequences.

This error should not occur during normal operation. It indicates a bug in the IronPLC compiler or VM.

Report this as a bug at https://github.com/ironplc/ironplc/issues with the .iplc file and the source program that produced it.

Think IronPLC is wrong about this?
