Created attachment 373742 [details] Crash report I started out using a mysql database on a remote server and got that working. Later, after my computer running GnuCash woke from sleep, GnuCash encountered an error while trying to save to the database, and I successfully saved the data to an XML file on the local machine. Since I want to keep the data in the remote database, I then used "Save As..." to attempt to save to the database again. After entering the connection information for the mysql database, I got a dialog warning that the database already exists, and asking if I want to replace it. Clicking "Yes" causes GnuCash to crash with a segfault. Saving to a new empty database works. This is consistently repeatable. See attached report. Also, mysql server is version 5.7.29 running on FreeBSD.
I've pushed a fix to maint that should prevent the crash, though there may be other misbehavior from trying to create a database that already exists. The fix will be in 3.906, releasing this weekend, and 4.0 and 3.11 releasing next weekend. Note that there will be no further work on 3.x after the 3.11 release.
