I have a test to get the column name and other metadata info from SQLite3 db. When I call sqlite3_column_database_name(pStmt, 0); my app crashes. This only happens when using it in conjunction with SQLCipher. The crash log isn't so helpful (as almost always with libs and ios).

I have problems with the device (iPhone XR 13.4.1) and simulator (iOS 13.4). I don't have older devices, but with simulator 11.4 and 12.9 I don't have the crash problem (although the method returns NULL, which is an expected result, according to sqlite3 docs, I do handle the null results appropriately).
My SQL statement is SELECT * FROM 'empInfo'. which has a working table with valid items.
Has anyone had any problem with SQLite3, SQLCipher, and ios13? Didn't found anything in SO or google...
If any more info help, just ask and I can add it.
Edit: I was able to reproduce the error in this project https://github.com/CarlinhaCamargo/SQLite3_crash_problem
