crash sqlite3

[Max-Job]

Good day In my project on objective c, crashes began to appear in sqlite3 on ios 13.2.3 and later devices. I use the latest version of FMDB / standalone. Maybe you have ideas, what could be the problem?

EXC_BAD_ACCESS columnNameForIndex: > objectForColumnIndex: > qL9١! > Attempted to dereference garbage pointer 0x10508ea60.

@Max-Job did you ever find out a solution? We're seeing the same thing with a different sqlite wrapper library.
