Message

Bytecode ended mid-instruction

The VM reached the end of a function’s bytecode while reading an instruction’s operand. This is an internal error indicating the bytecode is truncated or corrupted.

This error should not occur during normal operation. It indicates a bug in the IronPLC compiler or VM, or a version mismatch between the compiler and the VM.

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