RFR: 8350636: Potential null-pointer dereference in MallocSiteTable::new_entry

Tue Feb 25 09:46:06 UTC 2025

Hi,

This fixes a potential null pointer dereference in case of OOM. We return `nullptr` instead of `p` because I didn't feel like casting `p` from `void*` to `MallocSiteHashtableEntry*`.

I believe that this is a trivial PR, and I would appreciate it if a reviewer agrees!

Thanks,
Johan
