Is there anyway of turning off the command line switch -CR (Verify object method call validity) on a per unit basis in the same way that -Cr (range checking) can be turned off using {$R-}? I can't see any such directive in the FPC documentation.

As the title suggests, I have a specific problem in mind with the Firebird.pas file distributed with the Firebird source code. The code in this unit maps a C++ vtable into Pascal method calls (its not nice but it works). Not surprisingly when a program is compiled with -CR you always get a runtime error when a call is made to the Firebird 3 API, It ain't a Pascal vtable and whatever test the compiler uses fails.

I don't see a way around the Firebird.pas approach for calling the Firebird 3 API from a Pascal program and if there is no way of turning off this check on a per unit basis the -CR switch is probably unusable with any program that uses the Firebird 3 API.

{$OBJECTCHECKS off}

Many thanks - not the most obvious of switch names - but it works.
