1305617 - Gecko profiler add-on allocates lots of heap-unclassified memory in Linux

Status: RESOLVED DUPLICATE of bug 816598

(Core :: Gecko Profiler, defect)

Description

[Bill McCloskey [inactive unless it's an emergency] (:billm)]

Attachment: dmd-output.txt

When I start the browser, I get about 200MB of heap-unclassified in the main process. I'm attaching a portion of the DMD output I got.

When I disable the profiler extension, heap-unclassified drops to 34MB.

Besides the lack or reporters, this seems like a lot of memory for the profiler.

That looks mostly like summarised Dwarf unwind rules and so is not unexpected,
although I am surprised it takes up 200MB.
