crashlytics-ndk crashes when app exit

See original GitHub issue

Android Studio version: 3.6.1
Firebase Component: firebase-crashlytics-ndk
Component version: 17.1.0
ndkVersion: 21.2.6472646

Steps to reproduce:

When my app exit, by calling exit(0) on native code, the app crashes. After some investigation, the crash seems to be on crashlytics-ndk itself. Removing crashlytics-ndk (keeping crashlytics), stops the crashes.

Relevant Code:

I checked the source code from crashlytics-ndk, I might be wrong, but the problem seems to be detail::breakpad_context being allocated by a custom allocator on install.cpp:131 (function install_signal_handler), but it is being free’d by just calling delete on install.cpp:71 (function finalize, this is the line crashing).
