Coding question

[徐閔翊 Jordy Hsu <jordyhsu@xxxxxxxxxx>]

I have two questions about this file postgres-REL_12_2/src/backend/utils/mmgr/mcxt.c

We have used checkmarx to scan this file and we have checked this file already .

It doesn't have Improper Null Termination issue .

But we are just confuse why need to create two same function "palloc" and "palloc0"(figure1) and why don't use function "strndup" to do this action.

(figure1)

(figure2)

Attached file is checkmarx report .

This question is Improper Null Termination issue 475 (figure2).

I look forward to hearing from you.

Thanks.
