V9001¶

Code: V9001
Message: VM operand stack overflow

The VM operand stack exceeded the maximum depth declared in the bytecode container. This is an internal error indicating a mismatch between the compiler’s stack depth analysis and the actual execution.

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.
