i'm not choore that it does not return any messages if the database as errors, what i think (but not choore) is that this command does not print results to screen if the database as no error, meaning that it only returns results when they realy nedd to be displayed, but, onde again, not choore of this.

Can you try to pass the DBCC no_infomsgs in the database that gave you this error?

DBCC results for 'GMCDBGACCOMP_OLD'.

I would do the test, but i do not have a database with problems at this point.
