Using QSqlRecord to update QSqlRelationalTableModel - exception on destructor

[Enogma]

It does not happen if the line in the inner loop is commented out

Then put some debug output into the loop and/or only add some values and not all to see what happens.

using std::move

Yes, move semantics would be OK.

data->tableContents.size()

Is this a constant within the scope of the inner loop?

auto tableData = data->tableContents.find(row);

You dereference tableData inside the loop. Is this guaranteed to be a valid pointer?

This whole thing could be a red herring. too. It might be that there is an error somewhere earlier that has corrupted memory or the stack and is only manifest at this point in the code.

Thank you all.

I was left with two things to test, just took me a while to get around to it.

So i first wondered if i was setting a part of the relational database which was linked to a foreign key. Although this would probably cause issues later on, it was not causing this issue.

The issue was simple (and rather daft), i was trying to set a numeric parameter in the database with a string.

None of us have ever made that kind of mistake :-)
