Message

Constant pool index out of bounds

The VM tried to access a constant pool entry that does not exist. This is an internal error indicating the compiler emitted an out-of-bounds constant reference.

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.
