1942920 - [@ mozilla::FFTBlock::PerformFFT] | AddressSanitizer: hard rss limit exhausted

Status: NEW

(Core :: Audio/Video: Playback, defect)

Description

[Jason Kratzer [:jkratzer]]

Testcase found while fuzzing mozilla-central rev bd2ac8b50d75 (built with: --enable-address-sanitizer --enable-fuzzing).

Is it intended that setting the convolver buffer twice with the same buffer would lead to increased memory usage?

Testcase can be reproduced using the following commands:

$ pip install fuzzfetch grizzly-framework --upgrade
$ python -m fuzzfetch --build bd2ac8b50d75 --asan --fuzzing  -n firefox
$ python -m grizzly.replay.bugzilla ./firefox/firefox <bugid>

The attached testcase here was fairly unreliable during testing. I'm going to leave bugmon disabled.
