Description
-----------

Hello,

I occured a SegmentFault into a projet that use gb-db2-sqlite3 that does not happen when I use the old gb-db-sqlite3.
Tested with Gmbas DEB and Gambas v3.20.4 (Juillet) that procuce the same error.

I followed the procedure to produce the 'gdb' trace:

I also attached the little projet to reproduce ce issue and a video showing stet by step how to reproduce the issue.

Thank you
