…ythonGH-140111) Fix memory leak in sub-interpreter creation caused by overwriting of the previously used `_malloced` field. Now the pointer is stored in the first word of the memory block to avoid it being overwritten accidentally. (cherry picked from commit 59547a2) Co-authored-by: Shamil <ashm.tech@proton.me> Co-authored-by: Kumar Aditya <kumaraditya@python.org>
