[Question][Android] How to use for debugging? about hardened_malloc

[thestinger]

You could make a userdebug build of GrapheneOS for the emulator since we still have hardened_malloc on x86_64.

% repo init -u https://github.com/GrapheneOS/platform_manifest.git -b 14
% repo sync -j4
% source build/envsetup.sh
% choosecombo release sdk_phone_x86_64 userdebug
% m
% emulator

However, the memory corruption bug in whatever is causing it may be specific to arm64 and Android doesn't really support non-x86 emulator anymore.

Requires a Linux workstation with a huge amount of disk space and a decent amount of memory. Can reduce the number of build jobs if you don't have enough memory. https://grapheneos.org/build has proper documentation.

A userdebug build of the OS combined with a debug build of the app with native debug symbols would help with debugging it.

It's probably a use-after-free bug.

The issue in media_kit has been resolved, it turns out that it was a memory corruption issue that hardened_malloc was catching, which has now been resolved. :)

I think this issue can be closed.
