Strange error message while using Q_ASSERT

[homerun4711]

Hello!

I get a strange error message while compiling my project, it was working fine until I re-created the *.project file and the user-file from OtDesigner.

The error message is

error: no match for ‘operator!’ in ‘!record’
candidates are: operator!(bool) <built-in>

and points to the Q_ASSERT in the following code

QSqlRecord record = customerSelect->passRecord();
Q_ASSERT(record);

QSqlRecord record = customerSelect->passRecord();
Q_ASSERT(record);

To copy to clipboard, switch view to plain text mode 

If I comment the Q_ASSERT line everything works fine. Has someone an idea what is causing this error?

Kind regards,
HomeR
