What were you trying to do that didn't work?

Obtaining heap statistics from coredump is very difficult for application developers. Only expert with in-depth knowledge of allocator internals can obtain information like that provided by malloc_stats() from coredump.

Please provide the package NVR for which bug is seen:

glibc-2.34-82.el9.x86_64

How reproducible:

always

Steps to reproduce

1. Install gdb
2. gcore 1
3. Get information like "Total in use bytes" from the coredump

Expected results

It would be great if glibc provided a gdb script that I could source during the debugging session and would be able to easily get this information.

Actual results

No easy way to figure this out w/o looking into glibc internals.
