Missing Build Dependence: _freeze_module.c

Bug report

Bug description:

Build CPython by running "make".

Then a dummy pointer field to the end of struct PyConfig in Include/cpython/initconfig.h:

void *dummy;

Then, run "make" again. This time, you'll get a weird error from _freeze_module run as part of the build. Exactly what error you get will depend on how much you change the size of struct PyConfig and the system you're on. On my Linux system, sometimes it gave me an error about attempting to open() NULL (because the stack variable "inpath" from main() in _freeze_module.c was clobbered). Sometimes it gave me a path error.

Remove Programs/_freeze_module.o. Run "make" again. Marvel as this time make succeeds.

CPython versions tested on:

CPython main branch

Operating systems tested on:

Linux

Reproduce el problema con make después de añadir el campo dummy a Include/cpython/initconfig.h; después, inspecciona la entrada de compilación de Programs/_freeze_module.o y la dependencia de _freeze_module.c. Se considera terminado cuando un segundo make vuelve a compilar el objetivo afectado y finaliza correctamente sin eliminar manualmente Programs/_freeze_module.o.
