Advantage Database server crash

The following query makes an Advantage Database Server crash:

SELECT +SUM(0) FROM SYSTEM.IOTA

Note the + before SUM(0), this is the culprit. If I replace + by -, no error occurs.

If I execute this query in local mode, this error pops up:

poQuery: Error 7200:  AQE Error:  State = S0000;   NativeError = 2203;  
[iAnywhere Solutions][Advantage SQL Engine]
An error was encountered while reading an intermediate or temporary file.

I discovered the problem while testing and, even if I agree there is no point to add a + before an aggregation instruction, it should not crash the server!

Thanks

It is confirmed to be a bug. The combination of the unary positive operator and the aggregate function is the cause of the problem. It will be fixed in a future update.
