malloc profile from a core dump

[Ezolt, Phillip]

FWIW. ?

  For the older versions of jemalloc that was included with FreeBSD 7 & 8, I released the following gdb python macros:

We (Netapp) use it for both cores and live debugging.

...

I haven't updated it to the most recent jemalloc, so it would require work... but it may be a starting place for you.


Cheers,

Subject: malloc profile from a core dump

Is is possible to generate a malloc profile from a core dump? I'm investigating the use of jemalloc for pretty aggressive checking (a la libumem's auditing / redzone checking / ::whatis) for testing debug builds.

I've seen some similar questions in the areas (http://jemalloc.net/mailman/jemalloc-discuss/2015-June/001125.html) and some other tools in the area (https://github.com/argp/unmask_jemalloc) but nothing really appears to stick out.

Best,
~Alex
