Description

Problem*

Resolves #9267

Summary*

Return InterpreterError::PoppedFromEmptySlice if the length is 0 even if the slice does have elements.

Additional Context

The initial SSA calls the popping function with 0 length and non-empty slice. Works for ACIR and Brillig 🤷

  • No documentation needed.
  • Documentation included in this PR.
  • [For Experimental Features] Documentation to be submitted in a separate PR.
