Bug report

Bug description:

When building for Linux/X64, the 3.13 branch will not run successfully run python -m ensurepip if built with both --enable-experimental-jit and --with-pydebug:

git checkout 3.13
make clean
./configure --enable-experimental-jit --with-pydebug
make -j8
./python -m ensurepip

This fails with an error message like:

subprocess.CalledProcessError: Command '['/home/jglass/Documents/cpython/python', '-W', 'ignore::DeprecationWarning', '-c', '\nimport runpy\nimport sys\nsys.path = [\'/tmp/tmpsu81mj6o/pip-24.0-py3-none-any.whl\'] + sys.path\nsys.argv[1:] = [\'install\', \'--no-cache-dir\', \'--no-index\', \'--find-links\', \'/tmp/tmpsu81mj6o\', \'pip\']\nrunpy.run_module("pip", run_name="__main__", alter_sys=True)\n']' died with <Signals.SIGABRT: 6>.

Building with either config flag individually successfully builds.
