1. Have you saw crash in real device or only in simulators?
2. Do you use dynamic feature for language ID?

Tested on Android 12 Emulator with custom executor, but cannot repro this issue.

Second crash in the description is from a real device. Experienced it myself on two different Xiaomi phones, plus lots of crashes from users in the Google Play console.

Dynamic features are not used in the application.
As a wild guess, I have downgraded build tools from 31.0.0 to 30.0.3, compileSdk from 31 to 30, and moved all work with Language ID to the service in a separate process (just to be sure that crash can kill secondary process instead of main). This combination is in beta for 2 days by now and I don't see any SIGSEGV crashes.

Hmm, I feel the crash might be something related to separate/secondary process.
I also changed compileSdk and targetSDK to 31 but still cannot repro this issue.
Description
Version used: 2.2.2
Devices/Android versions reproduced on: Android emulator running API 28
I've included a sample project with a MigrationTest class that fails like so when invoking MigrationTestHelper:
java.lang.IllegalStateException: Migration didn't properly handle: user_fts
Expected: FtsTableInfo{name='user_fts', columns=[name, rowid], options=[]}
Found: FtsTableInfo{name='user_fts', columns=[name], options=[]}
Yet the AppDatabase_Impl sees the schema as being correct.
The root cause seems to be that they treat the implicit `rowid` column differently: the generated schema json file includes the `rowid` field causing MigrationTestHelper to expect its presence, but AppDatabase_Impl's onValidateSchema method doesn't check for rowid.
I believe AppDatabase_Impl has the correct behaviour in this case: MigrationTestHelper uses FtsTableInfo which uses `PRAGMA table_info()` to discover the columns of the fts table, which *doesn't* return `rowid` as being one of the columns, but MigrationTestHelper is comparing that FtsTableInfo with the json data which *does* include `rowid`, so it thinks the schema doesn't match.
