if i have an outstanding bench warrant, while i be taken into custody in an unrelated

my wife has an outstanding bench warrant for a felony case that she failed to appear at in the state of arizona a couple years ago.

she also is going to appear in court in a month on an unrelated child custody case.

what are the chances the court would take her into custody, or know about the other outstanding warrant when she goes to court on the other matter?

thanks
