Bug report

Bug description:

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

git checkout 3.13make clean./configure --enable-experimental-jit --with-pydebugmake -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.
