Thank you very much for your response and suggestions.
As you mentioned, the patch here is actually designed for glibc's ptmalloc2
andis not applicable to other platforms. I will consider supporting it only
on the Linux platform in the future. In the memory management strategy of
ptmalloc2, there
have any further insights or
recommendations, I would greatly appreciate your guidance.
Thank you once again for your support.
Best regards, Shawn
