What did you do?

Minimal steps to reproduce:

• Go to File → New In-Memory Database
• Create dummy table (anything that creates a savepoint/transaction)
• Execute pragma legacy_alter_table=1
• Select either option of the "Setting PRAGMA values or vacuuming will commit your current transaction" dialog (the outcome is the same) - execution will finish with errors
• Write changes (Ctrl+S) - a popup will appear ("The database is currently busy: executing query")
• Select either option of the "Do you want to abort that other operation" dialog (the outcome is the same)
• Application will freeze and has to be killed externally

What did you expect to see?

When aborting the other operation, a normal save
When not aborting the other operation, nothing

What did you see instead?

A total freeze/deadlock in any case
