> How are you measuring this? Many allocators, glibc especially, hang onto memory that isn't in use to avoid thrashing the TLB. They will reuse it, they just won't give it back to the system. I install an allocator and note down all calls to it. But I realized I had a bug in my call to `realloc` - I need to give it the layout of the _previous_ allocation, but I gave it the layout to the new allocation. Fixing that bug makes the realloc path work 👍 -- This is an automated message from the Apache Git Service.
