Simple program results in core dump

Pre-Report Checklist

• I am running the latest versions of pyQuil and the Forest SDK
• I checked to make sure that this bug has not already been reported

Issue Description

When running a simple program which parses and prints a Quil program, an error message is printed after the program.

How to Reproduce

Code Snippet

from pyquil import get_qc, Program

qc = get_qc("Aspen-M-3")
p = Program("""
DEFCAL I %q:
	DELAY q 4e-8
""")

print(p)

Error Output

DEFCAL I %q:
        DELAY q 4e-8

FATAL: exception not rethrown
[2]    20258 IOT instruction (core dumped)  python test-defcal.py

Environment Context

Operating System: Ubuntu

Python Version (python -V): 3.8.16

Quilc Version (quilc --version): 1.26

QVM Version (qvm --version): 1.17.2

Pyquil Version: 4.0.1

Start by running the provided Python snippet with the listed pyQuil, quilc, and QVM versions on Ubuntu to reproduce the fatal error and core dump. Trace the path used when parsing and printing the DEFCAL program; done means the program prints without the fatal message or crash, with a regression test covering this example.
