Solutions

Remediation/Fixes guidance: The issue is addressed in Qiskit versions v1.4.6 and v2.4.2. These are patched to error with a Python-space RecursionError exception once the expression depth exceeds the Python recursion limit which can be queried with sys.getrecursionlimit(). This limit can be adjusted by calling sys.setrecursionlimit(). Future versions of Qiskit may remove this limit entirely with a non-recursive version of the OpenQASM 2 parser.
